95 3.4 EGR SES problem.
Not sure if this should be in computer, or exhaust but here goes.
Oh, and I'm sure this topic has been beaten to death, but I couldn't search for EGR in the search field. Sorry.
Car is a 95 3.4l with way more miles than a gasoline engine should have, but i bought it a few weeks ago at a pretty awesome price. After putting more money into it, than I paid for it, I got it up and running pretty nicely... with the exception of one headache/problem I'm encountering.
Not that it's all that big of a deal, it's just a stupid light, right?
Anyway... brought it to the shop to read the codes.. since it's that stupid OBD1.5 system. Pulled codes 44, 64, 75, 76 and 77. So I changed both o2's and the EGR valve. I also noticed that the flex pipe that runs from the EGR output to the intake manifold was cut in two, so I went to the junkyard to find a new one (that was a headache and a half to change, i stripped one of the bolts, tried MAPP gas, tried ViceGrips... finally had to go to Sears and get some Bolt Outs. Awesome product BTW). Took it for a test drive.. still tripping the SES light. This thing has Pacesetter headers, if that helps.
So when I took it to the shop, it's still tripping 75, 76 and 77... EGR Solenoid 1, 2 and 3.
It only seems to do it when I'm coasting downhill. I'll be driving, once I take my foot off the accelerator, the light comes on. Any ideas? (Aside from "put black tape over the light") It runs fine, no more hesitation. feels like it has a little less power, but I suspect that's cause it's not running overly rich like it was.
