Hello,
I have some issues on 1997-E320. When I start the car in the morning doesn't take acceleration & backfires a lot.
I have to accelerate very slowly at low RPM or the car would hesitate and backfires.
I did change new spark plugs and spark plug wires,Transmission fluid was replaced with new oil filter (sometime in high speed does not respond fast hesitate ).
But still same issues,the engine light does not came on and the car has 156K miles.
I just got the car,no any records in the car.

What can be AMM??? OR ???

If is AMM is there any way to test it ???

Any good thread about AMM ???

Thanks Guys.
