Why would your 2004 Sunfire be over revving?
your sunfire is revving if the idle is set to high, or when adjusted. the idle is high also when the engine needs to warm up in cold weather. there is also the possibility that the engine temp sensor needs to be replaced, for it is not relaying proper heat temp. the light on your dash may show you engine temp, check this. if unable to do this yourself, you may need your cars manual.
Where is the water pump on a 2002 sunfire?
My 2002 is a 2.2L and the Water Pump is on the (standing in front of the car looking aft-towards the back) left hand side. Locate the Serpinetine Belt and it's right underneath and just aft of the alternator pulley.
This could be caused by a lot of things. If it was my car, I'd start by replacing the fuel filter, checking and, if necessary, replacing the plugs and checking/replacing the plug wires. I'd also run a bottle of injector cleaner through the system in case the injectors have gotten dirty or clogged. (I do that every few months just a matter of course) If these things don't solve your problem, I'd suggest taking it in to a diagnostic center as it could be a sensor or a computer problem. Let us know what you find! FriPilot
Spark plug gap for a 2000 Pontiac sunfire?
The plugs on 2.3L and 2.4L OHC engines the gap should be at 0.050 in.
The upstream 02 sensor is usually located shortly after the exhaust manifold, before the converter. That is the one that controls how the car runs. The downstream sensor, after the converter tells the computer if the converter is doing it's job or not. It does not affect performance, but you might have to live with a check engine light being on. There are probably 2 of each on a V6.
Why does the check engine light flash on a 2003 Pontiac Sunfire?
If a check engine light is flashing that means an engine cylinder misfire has
been detected
Where is the the throttle positioning sensor on a 2002 Pontiac sunfire and the part number?
Its attached to the throttle body and should have about 4-5 wires going into it, it also should be near the end of the throttle cable
Your Pontiac Sunfire 98 overheating what to do?
I had this problem with my 97'. You should check the oil make sure it hasn't turned to what looks like chocolate milk yet, if it has you might as well start looking for a new car. Replace the thermostat they are not expensive. If these things fail it could also be your head gasket or the head. If it is the head you are looking at $2,000 for repair. but if it is just the head, you might have a chance like I did. Luckily mine was a pinched line. Also check your lines. But a over heating problem is also hard to find.
How do you change a starter on a 98 Pontiac Sunfire?
Note:It may be necessary to remove the exhaust pipe(s) or frame crossmember to gain access to the starter.In extreme cases it may be necessary to unbolt the mounts and raise the engine slightly to get starter out
- Disconnect the negative battery cable.If the vehicle is equipped with a delco loc 2 or theftlock audio system make sure to have the activation code before disconnecting the battery.
- Raise the front of the car and support it securely on jackstands.Apply the parking brake and block the rear wheels.
- On 2.2L engines with manual transaxle remove the brace between the engine and the transaxle.On 2.3L and 2.4L OHC engines remove the air intake ducts to gain access to the top starter motor bolt locatedon the transaxle
- Remove the mounting bolts and detach the starter.Note the location of the spacer shims they must be reinstalled in the same position (if used)
- Working under the car clearly label then disconnect the wires from the terminals on the starter motor and solenoid

How much does it cost to replace an exhaust system on a Pontiac Sunfire?
This is going to depend on what degree of quality you demand in a muffler, and how much of the system needs to be replaced. If you need new pipe from the header on back, and you need to replace hangers, it's going to be real expensive.
I'd take the car in to a muffler shop for an estimate and go from there.

Where are the spark plugs located in a 1997 Pontiac Sunfire gt?
It should be the 2.4 in that case they would be under the quad 4 covor on the top of the motor that holds the module and coil pack in it. Just pull the bolts out of that silver covor and pop it off and they will be right there where you can see them but you will need a 6" extention with the socket to pull the old plugs out and don't pull them out while the engine is hot.
Somewhere on the belt there should be a tensioer that is mouted to the engine or the alternator bracket. Turn it counter clockwise with a 15mm wrench and it should lift the tensioner enough to slide off the belt.
On my '96The tensioner is down and to the left of the alternator (looking at the engine from the passenger side fender)I had to replace the alternator just this weekend. The tensioner is loosened by putting a 15mm wrench on the center nut and rotating it to the right (toward the front of the car)
What does the ETS switch do on the 2003 sunfire why and when would you need to use it?
Its a traction control switch...when your slipping usually your tires spin when traction control is on it lets the other tire spin just as fast so you dont slide as much and get more grip. Use this when the roads are hazardous, snow rain etc.
Can i vacuum out oil from spark plug wells with wet dry shop vac on a 1999 pontiac sunfire?
On the face of it, this sounds like a pretty good idea. But I'm not so sure it really is. You might end up sucking oil out of the cylinders, leaving them dry at the next start-up. Granted, the oil in the cylinders would be replaced quickly, but it just sounds risky to me. It's one of those ideas that just sounds wrong, but you're not sure why.
I guess I'd just try to poke a rag down there and sop it up.
Answer
Yes. Just leave the plugs in. Although you would find it easier to just manually suck it up a clear narrow bore tube, making sure you don't swallow any.
Where is the transmission dip stick on a 2002 pontaic sunfire?
most sunfires do not have a dipstick for transmission fluid. (called Transaxle fluid as well)
You are supposedly not supposed to fill it unless getting your fluid changed or getting a repair. I must say with my 2001 sunfire I have never added fluid and never had a problem. There is a little red knob that you turn to fill the fluid and you can buy and add a dipstick (usually only from a dealer). That knob is found by looking straight down in front of the brake cylinder on top of the transmission. It is pretty hard to snake your hand down to but you can do it.
Hope that helps.
How do you change a license plate light on a 1998 Sunfire?
You have to remove the tail light lens cover from inside the trunk- there are about 6 nuts holding it on --the whole cover comes off and bingo there are your lites for the Pontiac emblem that lights up!! There are no lights persay just for the Licence plates on my 96 Sunfire and I assume the same on a 98
How do you clean a Pontiac Sunfire CD player?
Inside or outside?
Outside is pretty direct. A damp cloth usually does
the trick.
If the inside is dirty, I'd buy a CD lens cleaner and use
it. That will solve any crud on the lens problems.
If the inner workings have become dirty due to
blowing dust or something, You may have to yank
it out and have an auto audio shop clean it up for you.

Why are the low beams not working but high beams work on a 1997 dodge caravan?
Replace the bulb. The low beams and high beams use separate parts inside the bulb.
If replacing the bulb does not fix the problem, check the fuses.
