Well if anyone remembers me I have had quite a number of problems with my 95 1500 truck. It had a blown plenum gasket, warped intake manifold, PCM was fried, etc. I bought a working PCM online, then replaced the intake manifold with the hughes setup.. I have pretty much replaced everything on the truck now.-lol. Being that the hughes intake doesnt have provisions for the EGR valve, I specifically told the company I wanted the pcm to be non EGR valve. I also told them standard tranny. So the first computer they send me was for an automatic, and flashed error codes. I called thenm and they sent a replacement computer. Well this time they had the tranny right. But, even though the pcm had a label on it saying non egr, as soon as I plugged it in it flashed a code for non working egr valve. So I put up with that for now. This was last september. It also said the camshaft sensor in the distributer was faulty. I replaced that, unplugged the negative on battery to reset the computer codes. Then I still get the egr valve problem, but now I get code 27 which says its the fault in fuel injector circuit. I replaced the fuel injectors, the wiring to the fuel injectors, and now the connectors, and I STILL get this code 27!!! GRRRRR. I have unplugged the negative cable to reset several thousand times now, but almost as soon as I start the truck code 27 sets off again.
Can it be that maybe the computer is screwed and it just needs reflashed after going through so many troubles??

 

how does it run ? good or bad?

 

There are no OBD1 PCMs without EGR.

 

? anyone make an EGR simulator to silence the CEL ?
