How do you eliminate the egr on a 1994 GT so the check engine light doesn't come on?

thats a waste of money.

 

really... why's that...

 

because i had it, and it still generates error code #33. and plus you can just leave it hooked up and if you sit it in the right place it wont make ur CEL come on.

 

heres a couple pics.

That is how the system deletes the EGR system, by generating that "failure" code (or 332 in the '94 3-digit code format), but not turning the CEL on. Having that only code in memory does not affect spark and A/F tables, it simply bypasses the EGR function.

 

do ONLY hard codes or keep alive memory codes effect a/f ratio? OR BOTH
aka the ones that set the light, and the ones that only appear in a scan

 

Another easy fix is to take the check engine light bulb out. (i did)

 

So basically the only thing that plug does it stop the CEL from comming on?
