1993 3.2 ATX CE light comes on

[Bruce M]

Picked up a 93 w/ 108,000 on it. Check engine light comes on only while you have been driving for about 10 minutes or so and will not go out untill the car shut down. Will not come on sitting still during idle even when reved up. Pulled codes and they pointed to O2 and EGR, changed both O2s and tried used EGR, diaphram seemed OK. Cleaned and checked intake including MAF still comes on. Runs rich but smooth. Plan to put car on better scanner this weeked to get more info, anyone seen this before, any suggestions as to were to look?

Can i point a possible intake or vacuum leak?

There are (3) components to the EGR system, plus you may have clogged intake nostrils. If you get stuck, let me know, take a swing down to northern RI this weekend.

Post the exact codes, not conclusions.

NONE of the code charts done tell you what to replace, they are only a step in the diagnostic process. Your most important diagnostic tool has to be your brain, not a better scan tool.
