Is there an egr valve on the 2.2 ecotec in a 05 Chevy Cavalier?

Watch this GM 2 2L Ecotec timing chain replacement 03 Cavalier part 1 Intro and valve...

On your intake manifold, #3 in diagram. My info showed two wires, one is gray, the other is orange with black tracer.

It is the same engine you could install your cylinder head and manifolds to get rid of egr plumbing or remove valve and install block off plate.

Call your chevey dealership with the vin number that should be able to help.

Where is the EGR valve on a 2011 CHEVY Equinox? LS 2.4L

how old is your battery? that might be it also.

check your throttle sensor

the egr valve is located on the drivers side next to the fuel rail. here is a picture of the valve

The spark plugs on the cavalier are under the 2.2 ecotec panel located on the top of the engine. There are no spark plug wires to deal with. The electronic coil pack directly attaches to the plugs with rubber seats like in a spark plug end. Then you use a deep socket ratchet to get the plugs out. Use anti-seize compound when replacing the plugs.

There are several engines that will fit the 2.2l Ecotec, 2.4L high out put motor, and I have actually seen a chevy cavalier that has a 3800 V6 in it if you want to go all out but in most cases sticking with the ecotec motor or the 2.4 High Out Put motor would be best they are two of the best motors for these cars and since the Sunfire is basically the same car as the cavalier almost any thing motor wise is inner change able between cars depending on the motors i own an 2004 chevy cavalier LS sport and a buddy of myn has a 2004 Pontiac Sunfire and both have the 2.2L Ecotec and are both Manual trans and even most of the interior parts are the same except for some of the dash board components hope this helps you out
