Where is the EGR valve on a 98 Cavalier?

I purchased an EGR valve for my 2000 Cavalier and couldn not find it either. So I went to autoparts house and they looked to no avail. Then went to dealer who also could not find it. Hmmmmmmm, alas it does not have one. Why? Well, it is my understanding that certain government vehicles do not require one. Was mine one of them. I don't know. But I can tell you that all EGR valves are bolted to the manifold, and for cavaliers it is typically on the drivers side of the engine. Good luck with this one.

Not all cars have an EGR valve, government or not. It depends on the engineering designs of how cool the engine runs, and how much NOx is produced under load. If not a lot is produced in the first place, the converter would likely take care of it nicely.
some years makes models did not have one.

such as the 1992 3.8L engines for example

and others.

government has nothing to do with it. some of these engines with the pollution controls they were built with put out acceptable levels of nox and otrher gases low enough to not warrant the need of an egr valve.

Car Stalling Problems

Why would a car stall when idling at a stop light?

If the car runs fine while driving and cuts off ONLY when you are idling (foot completely off the gas pedal and RPM's at idle speed) then your idle air control valve my need adjusting or need to be replaced, or idle air passage make have been blocked off by excessive carbon build-up. If build-up is the problem, a good removal and cleaning will do the trick or an off the shelf spray cleaner may get the job done as well.

Could also be clogged fuel injection system. Try a fuel treatment with a full tank of gas.if a older model GM front wheel drive it could be the lock-up solenoid on the transmission. or it could be a stopped up catalytic converter on about any make and model.

First thing id do is check and change the fuel filter, its usually checked by blowing air through it (in the arrow direction) if no air flows through or it blows through slowly then its more than likely plugged change it and go from there. sometimes after all avenues have been followed and the problem still exists i have seen the sock on the fuel pump be plugged and do the same. it will run great while accelerating but stall at idle due to not enough fuel pressure.

It could be a problem with the car not getting enough fuel, or it may have something to do with one or more of the sensors, such as the Mass Airflow Sensor. Is your check engine light on? If it is then its most likely a faulty or dirty sensor.


Please chect the EGR valve to see if it is stuck open with a chunk of carbon. This will cause an internal vacumn leak and the car will not idle. To test the EGR valve (Exhaust Gas recirculation) pull it off and try to blow thru it. Also look to see if the EGR pintle is seated. If the car you are having the problem with is a Chrysler then the plate that seals the EGR will likely be completely missing. The fuel filter will not cause this problem as the fuel demand at idle is very low. A clogged Catalytic Converter will also not cause this problem.



AGREE! well kinda because i know for fact Catalytic Converter is not going to make your car do that. The most common reasons are :Idle Air Control Valve, Mas Air Flow Sensor or the EGR valve. Make sure the throttle body is clean. Use only Throttle Body Cleaner. Check your Air Filter make sure its not dirty. And try to Flush your engine every 100,000 miles.


If you are having problems with starting your car, the car stoles on you as you drive or come to a stop sing, the serive engine lights are on, then you have a problem with 2 sensors, camshaft & crankshaft. You need to replace them both. If you take to a mechaniv shop or dealeriship it will cost you between $300-$500.

I and a bunch of my friends had same problem. I fixed my car and my friends car, and then friends of my friends started to call and I began to fix this problem for them at 50% cost less than of a shop/dealer.

If you live in Toronto or GTA, please call me now at 647-831-2102 . The car must be cold in order to work on it, so it is better that I come to your place. It is a dangerous problem and you should fix it right away.

Call now 647-831-2102



I had this same problem in my 1992 Buick LeSabre several years ago. The problem is: Fuel Pressure Regulator. The reason this happens is that when driving at highway speeds, your engine reguires more gas. There should only be a vapor at low speed or idle. When the fuel pressure regulator is at fault, too much gas is being dispensed, flooding your engine. My mechanic only charged me $100 for the part, but did not charge labor because it was easy to get to it. I went to Riches Auto in Tipton, IA and John fixed the issue. I took the car to European Automotive in Rolling Meadows twice and paid $80 both times, but he could not diagnose the problem. As a result, I have always gone to John at Riches Automotive. Anyway, check and replace the fuel pressure regulator. Let me know how this gets resolved. Thanks.

What causes a car to hesitate?

Are there particular circumstances when it hesitates? (engine hot or cold?, damp outside? certain speeds?, from a start?, etc. How many miles are on the car? Is the check engine light come on? When was the last fuel filter installed? When was the last time the throttle body was cleaned? or air induction service done? Open the hood, look at the back of the engine on the driver's side, is there oil seaping about 6 inches from the top of the engine? What did the spark plugs look like when you changed them? When were the wires last changed? Do you keep an eye on the oil level? Does it consume oil? What is the 8th digit of the vin? these answers will help.

Check for leaking hoses such as vacuum hose. Check the spark plug wires, are they connected properly, are they too old. take out all your spark plugs and check each one to see if they have enough gap at the end of it. not enough gap can cause a miss fire. do a fuel pressure check, with a fuel pressure gauge. if your car hesitates during start up, check you camshaft sensor. if you have a diesel car, check you glue plugs. its located beside spark plug

Oil weight for 93 Mazda Protege?

10W 30, 5W30 in >32 degree constant weather (winter up north). On a car that old, I'd go with something slightly heavier unless you've had your engine rebuilt recently - 10W40 would be smarter IMO

How do you know when the fuel injector goes bad on a 1997 Mazda Protege?

there is a certain tool that will detect a small vibration. check each injector with this. no detection will determine the faulty injector IT WILL TELL YOU. no it wont tell you. take a long screw driver, and put the metal end on the top of the injector with the engine running. if you hear a small clicking noise, then it is working properly. make sure you check all 4 injectors

How do you remove the stock stereo in a 1991 Mercury Capri?

hi, the four little holes in the front of the stereo are for 2 special tools. they are cheap (i think) and most shops have them around. it only takes 2 minutes to remove with the tools, so it shouldn't cost much to have a shop do it if you dont want to buy the tools. hope that helps

you can get the u shaped tools at walmart for about 7 bucks in the car stereo section wamong the installation kits.

I'll add you insert the two tools until you feel the first click. Then push each tool outwards towards the sides of the stereo which releases the catches. While doing that then pull straight out. The tools are readily available anywhere they sell stereos.

Where is the EGR valve on a 2000 Toyota Camry I4?

The EGR valve is a round "valve" (has one hose coming from top, one from side) that is on top of the throttle body. Actually, it is bolted with two bolts to the rear of the throttle body. If you don't know what a throttle body is, look for the pulley that moves when you press the gas pedal (with engine off). If i remember correctly....there is no egr valve on a 2000 Camry. If there is however it will be where the last guy said. The link below is to a picture of the EGR valve for a 2000 Camry 4-cyl. engine with an automatic transmission. It is bolted to the back side of the intake manifold with two bolts, and to a flange at the top of a steel tube running up from the exhaust system with another two bolts.

What might cause a '92 Toyota Corolla to die when you give it gas but idle fine?

clogged fuel OR air filter,vacuum leak,probably to the distributor,clogged muffler or resonator if you've already checked the catalytic converter.Is it automatic???

would have to agree with that most likely clogged fuel filter

Change your fuel filter because your filter is all clogged up.

Does it do this after running for a while? I had a similar problem which was down to overheating (which in turn was due to a loose head). Theory goes that the fuel in the carbourettor was evaporating due to the high heat - after letting the engine cool for half an hour it started again. May or may not be the cause but HTH

Fuel pressure regulator may be bad, also check the spark plug gap.

What is the timing order on a 1993 Mazda Protege?

firing order for the 93 is; 1,2,3,4, when you are standing in front of the car left to right. if the distributor is on the car the order is (standing on the drivers side looking to the passenger side) bottom left connector is 1. the rotor turns counter clockwise so 2,3,4 accordingly.. hope that helps.. This is what the Hayes manual says, but it isn't right. I had to solve this myself last year. They cyl. order is left to right 1, 2, 3, 4, but the actual fireing order is 1, 3, 4, 2. I believe that the 1 is the one closest to the front of the car on the distrubitor and going counter-clockwise. I wrote them on my distibutor cap so I won't have the problem again. I learned from a friend that inline engines seldom fire 1,2,3,4. as the crankshaft doesn't work that way. -TWO780a

How do you repair a misfire code on a 1997 Mazda Protege?

I had the same problem just two months ago. Turns out that when the techs have been changing my oil, some was leaking into the spark plug chamber next to the oil filler cap (forget which spark plug it is). I pull the boot and found that it was oil soaked. So, I did a tune up to my car (needed it anyways) and problem was solved.
