Will bad egr valve cause vehicle to stall in hot weather?
Even a good EGR valve may cause an engine to stall in hot weather.
How do I remove and clean the EGR Valve on a 1997 Geo Prism 1.6L 4cyl?
Remove the EGR valve vacuum lines. Remove the EGR valve retaining screws. Wash the EGR valve in hot water. Allow the valve to thoroughly dry before installing it.
How hot does the flow tube on a EGR valve get?
as hot as the exhaust manifold there are exhaust gases passing through it
Why does your 99 f150 stall when its hot?
Try cleaning the Intake Manifold where the EGR valve is attached.
Why would a 1996 Ford Contour idle rough once it gets hot?
possible vacume leak in the egr valve or bad valve itself.
What do the letters EGR stand for and what do they do?
EGR stands for Exhaust Gas Recirculator,and it basically is a valve that circulates hot exhust gas in the air fuel mix to make the engine run smoother when cold .
1994 Ford Taurus 3.0 liter engine you just replaced your EGR valve and backpressure sensor because the exhaust line to the egr valve and sensor was getting so hot it was melting the sensor what else?
You need to find some kind of asbestos wrap or make a small heat-shield guard to put on or around the exhaust line to the EGR; thus preventing this from occurring in the future. Your catalytic converter can have blockage as well which will cause all these problems
How do you fix a 95 Chevy z28 that runs good but once it gets warm the RPMs start going crazy and it starts running like it is misfiring and the coil has been replaced?
my rpm went up and down when my 1994 Z28 engine got hot , I troubleshot to at stuck EGR valve, the valve was packed with carbon deposits. I removed and replaced the EGR valve and the EGR solenoid and cured this long time problem
Why is your EGR getting really hot?
The egr (exhaust gas reclaimer) has hot exhaust gas passing thru it, it will get hot.
Why would the engine temp go up when idle only when it is hot outside and a check engine light for egr valve flow malfunction?
Hey Michael==Make sure the cooling fans are working properly. It varies with the make of car. GoodluckJoe
What is the parachute valve at the top of a hot air balloon is used for?
The valve allows hot air to escape, slowing the ascent of the balloon, or if the valve is left open long enough it will cause descent.
Where is the egr valve located on a Nissan sentra 1994 and what are some signs of it going bad or getting stoped up?
Location of EGR valve is between the fire wall and the engine, under the intake, toward the rear or transmission end. Look for the rubber hose that runs from the air filter to the intake inlet. Look under the hose down to the right and you will see it attached to the exhaust manifold. The exhaust manifold is under the intake. If EGR is leaking your car will idle poorly and the exhaust gas inlet tube will be really hot. You can test to see if its stuck shut by placing your finger on the diaphragm and rev the engine over 2k. The diaphragm should lift. If it doesn't lift the valve could be stuck. Remove vacuum line put 15 of vacuum to EGR at idle. Car should idle poorly or stall. If pass then check for vacuum at EGR vacuum line. Place vacuum gage on EGR line, rev fully warmed up engine to over 2k, you should get vacuum! If no pass, then check BPT valve and EGR|Canister solenoid. To check BPT remove EGR vacuum line put line from BPT to mouth, rev engine to 2k, it should suck. If you can blow\suck and it leaks the valve or exhaust line going to the bottom of valve is bad. To check solenoid rev warm engine to over 2k use mechanic's stethoscopes, should hear click. No pass, unplug and put 12v to solenoid, put solenoid vacuum line in mouth, blow\suck? Pass check continuity from solenoid to ECU. Everything working but still get EGR code remove Exhaust Gas Temp sensor. Place in hot water check with ohm meter should be big change between hot\cold temp sensor. ECU checks EGR by opening solenoid which should open EGR valve. When EGR opens hot gases hit temp sensor causing a change in resistance, ECU sees the change and then sets an EGR ok. If ECU opens EGR solenoid but there is no change in the Exhaust Temp sensor ECU sets the MIU light with EGR code.
