Okay, I have a 98, V6 automatic with 89k miles. I have a KKM Intake, I removed the resonator, and I have a Flowmaster muffler.
Like many Contour owners, I have the CEL. I had the O2 sensor replaced, but the CEL is still there. Even after a tune-up (new plugs, plug wires, PCV valve, oil, and fuel filter), I am getting the CEL.
I've lost faith in my mechanic, now, because he seems to want to get the car out of the shop rather than do the work. He ran the codes and told me that the EGR is returning a bad signal and that the O2 sensor in the "second bank" is running lean.
With relation to the CEL, what I notice about the car from driving it is as follows:
1) Sometimes a rough idle when put in gear
2) Unusual smell to gas (bad gas smell)
3) Sluggish and lack of smoothness at lower RPMS, and it doesn't have the kick at the higher RPMS.
When I reset the computer (pulling the PCM memory fuse), the car runs fine for about a half hour, then the light comes on and everything gets bad.
I've read alot about the IMRC module, EGR valve, and the infamous O2 sensors. However, I am no mechanic. What do I do? Any help is appreciated.
