Hello everyone, i need help with my 1999 Cadillac Deville. I've owned it for one year now. Currently has 96,195 miles & had 94,300 when i purchased it. I have only done one oil change and regularly drive 4 miles to work, four back. Two weeks ago it began stalling because it was low on oil (about 1 qt) The check engine light came on first and then the oil light after stalling a few times. I topped it off to the correct level and the stalling seemed to stop. The oil light went away but the check engine light stayed on. The car normally idles at 625/650 rpm and is spiking down to 500 and sometimes randomly drops to 0 were it stalls... It runs around 200/215 F*. After reading a similar post could the wires plugs possibly have something to do with it? NorthstarAJ mention it in a different post, "Bad plug wires cause 4X codes and stalling" 2nd page. I attached a picture of the only funky wire that i could find and one of my plug wires. Also, before all of this happened the car seem to jerk in between the speeds of 30mph to 40 but it never stalled or had any check engine light come on. I pulled the codes and got (1350 ECM engine component module/ Ignition Control System?), (1375 - crankshaft sensor), (1377 - IC Cam Pulse To 4X Reference Pulse) and (0404p - EGR exhaust gas recirculation Open Position Performance). Thank you for any help, information i can get.
My 1996 Deville has the engine light on and will not pass emissions. My dad's car, he thinks its a bad ground? The repair shop wants to replace the PCM at a cost of $502 pluss around $300 for installation and programming. I found one on Ebay for $89.95 programmed. Anyone familiar with this issue? Please help.. Phil

When going down the road at operating temperatures, while giving just a small amount of gas the engine seems to stumble or missfire, and sometimes even will completely stall after you take your foot off the pedal. When I unplug the EGR valve it works fine, but when I plug it back in the troubles come back. Already tried replacing the EGR valve but it had no effect. Any suggestions?
