CEL after maintenance

[bglz42]

Had to start the car to move it into my barn yesterday. Checked for code first, nothing. Started and ran fine.

I think I will start from the beginning...

Check air filter
Check MAF connection
Check all connections at coils and O2 sensors.


Thanks for all your replies!!

Your car is almost like mine, 2001 with 38k on it. I had to replace my MAF sensor, it went bad and it fixed my CEL for a lean engine fault. Since you changed your O2 sensor, try getting a new MAF and reset the ECU. She should run just fine after that.

The thing to remember here is that the CEL codes are not always 100% accurate, any good mechanic will tell you. It nearly points you towards the area that could cause the fault but it could be upstream or downstream so first change the least amount in parts with the biggest influence in engine performance = MAF sensor.
