All, we hook CWO's car to the CODE Reader and got lots of codes 34,14,... all leading to his EGR, Once we replaced it, we ran the CODE Reader again and all his fault codes were gone. Hope it fixed the problem?
OK, yesterday I went to el prezidente's house and checked the codes. Code 34 flashed, EGR, and we went and picked up the valve and valve positioner from autozone. The car also flashed codes for low MAF voltage and speed pick-up. Speed pick-up is obvious due to nothing attached to trans (MAF conversion from speed density) and low voltage to MAF I believe from overheating. Here are the two symptoms that gave away the EGR problem...other than the obvious code.
1. Cold air intake was hot to the touch, to the point it would burn.
2. Spuratic engine temperature. The gage was traveling between 40 deg of temp change as I was driving.
When I slowed the car shut down. EGR was stuck open and routing hot gases into my intake which eventually shut down my engine. The car ran fine last night and the temperature was rock steady. I truely believe the problem is resolved now.
Lesson Learned: Buy my own digital code reader!!!!
