If you mean disconnecting the electrical leads, Absolutely. If vacuum actuated, you'll have to plug off the active (sucking) end of the hose. If your egr is stuck it will probably run better. You will get a check engine light and won't pass emissions though...
Blocking off an EGR valve can make the car run rough. The fuel mileage can suffer as well, since the car is designed to have the EGR valve operable.
A faulty or clogged egr valve can cause an engine to run rough. If stuck or clogged the valve can be cleaned after removal with carburetor cleaner.
Check the EGR valve. It sounds like your EGR valve is staying open. An EGR valve that is open at idle will cause a car to stall. An EGR should be closed at idle and open when you are driving around.
Yes,you can,just plug the vacuum hose with a screw or something
Yes, your car will run without the EGR valve but there could be some side effects. The EGR burns exhaust gasses which inturn reduce the combistion temp. So you may get lower gas mileage and your car may ping (preignition on acceleration). If it pings get the EGR replaced, pre-ignition will destroy the pistons and rods.
can you clean a egr valve on a 1995 pontiac firebird with a 3.,4 litre motor
A sticky or malfunctioning EGR valve could make the engine run poorly but it should start.
Yes no problems, you have to make up a blanking plate to bypass the egr
AnswerIt's under the EGR modular. The EGR modular is on the top of the engine on the passangers side close to the fire wall and looks like a black hockey puck. Follow the very short vaccum line off of it to the EGR valve. 2 hoses run to the EGR switch and the bottom 1 runs to the EGR valve.
Need to check the EGR VALVE.
Yes
the vacuum switching valve that run the valve are a common problem they are intermittent stuck closed so do not operate the valve
