Hi All,
I have an intermittent problem that causes the engine to stutter and not rev smoothly.
The car is an 87 325is with a fresh top end re-build and new rings. It runs perfectly and drives like new 99% of the time. Very occasionally it will give just the faintest hint of a stutter while you are driving. In a super rare event, the engine will not build revs smoothly. When you push on the gas the revs go up and down as you see in the video and it will hardly build any revs. Trying to drive when this is happening is damn near impossible as the car jerks badly. After an attack of around 10 minutes, it went back to normal and I was able to drive perfectly smoothly home.
Advice is appreciated.
We have replaced the 2 main relays and cleaned lots of contacts and grounds, but there may be more. We have also replaced the crank position sensor and got a reading from the tps that is in spec. The battery and alternator are good.
Thanks!
