I have a 1995 SL500. CEL came on - checked codes - MAF out of range. I did the following:
- Checked wiring harness for shorts/opens and intermittants - harness OK
- Cleaned MAF - Reset codes - Ran without CEL for a day - CEL on again
- Checked codes again - MAF out of range
- Ordered Bosch rebuilt AMM
- Car drove ok for a day or two with CEL on then began to stall. Disconnected MAF and the car ran great
- Replaced AMM - CEL went out - car ran great for two days
- After filling up my tank, the car stalled and would not start again
My question is, before I send the AMM back, is there something I sould look at.
I'm driving with the AMM disconnected and the car runs great.
Thanks
