Low wierd power
I have an E36 325 without vanos.
The problem is that when I run on regular speed, I can feel power ranges 80-100% can also see it on the economy gauge that fluctuates.
i have change air flow meter and oxygen sensor. but i stil got the problem . enginen and transmission have run abourt 280.000 km. i tryed to drive without air flow meter but the problem is stil the same. over 4000 rpms its getting better but when im change to next gear it lossing power again.
what could be wrong?
