it seems that someone in the other forum told me that my 94 camro is an LS1, well heres my sitc. got a new EGR valve and now my check engine light is on saying its my EGR valve. well my Valve is past its return policy. and I highly doubt an 5 months old EGR valve (electronic) would break where a 10 years old EGR valve(electronic) lasted that long. any suggestions? on why it would trip my light, other than the most obvious of course. also those EGR arent cheap.

car is still stock, slowly working on it.

1994 Camaros came with LT1s, not LS1s unless someone did a LS1 swap to yours. Anyway, on LS1s you can just remove all that EGR bullcrap and lose about 15lbs of weight. All that will happen is the check engine light will come on but wont change how the car runs.

your LT1 will run just fine without EGR, buy some $15 block off plates and remove that junk.

your OBD1 PCM might not even notice its missing.

I live in california...so I need my EGR valve. those electronic EGR valve are pricy. can it be a faulty wiring in the system thats causing it?

A mechanic who doens't know LT-1 or LS-1 cars too well won't spot a missing EGR. You'll also pass emission just fine without it.

so, your car is an LT1 or an LS1 transplant? its a '94 so it should be an LT1 (in which case this thread should be moved to LT1 tech). the LT1 EGR valves are not electrically operated, they are vacuum operated. there is, however, an electronically operated vacuum solenoid (that is mounted separate of the EGR valve) that opens or closes the EGR valve. later!
