3100 EGR delete without check engine light.

[ceaspaece]

The threads on the fitting for my EGR tube at the exhaust manifold no longer exist. The tube isn't available anywhere. Figured at this point I'd just delete the EGR. Are there any ways to trick the car into thinking there's still an EGR so I don't have annoying check engine light?

Short answer, not really.

Long answer, yes but I'm not nearly smart enough for that and I think the number of people that mess with the 94/95 ECMs is in the single digits.

I would like to know as well.  I pulled it off the Monte, but it ran like crap, so I plugged it back in.  It's just sitting there plugged in as it's been blocked off.

I had the GTP programmed to ignore it, but then I didn't delete it, so I had it added back in as stock

RobertIsaar was the guy for this. He did all kinds of non-sense to my CSC.

3100s were tougher.  94-95 3.4 DOHC still had socketed MEMCAL/PROM.  3100s on the other hand, I believe they were flash PCMs like the 96 OBD II PCMs.  I don't know that anyone ever got into the flash PCMs.
