Hi all,
been a proud e30 owner (various models) for over 25 years. My latest though is driving nuts.
The car is a 1988 320i convertible automatic. I recently finished restoring the car and found a leak from the auto box after it had been rebuilt. So I took it back to the shop to have the leak fixed.
They fixed the leak, but as I was driving the car back home, it started loosing power and hesitating and eventually the more I depressed the accelerator the more it hesitated (will not rev) and started back firing and then eventually stalled.
I then put the car in Park, it started and idled perfectly, I put it in drive and start driving only to act up again. Turned the car off and back on, it happily idles and revs to redline in Park and Neutral, as soon as I engage any gear, drive it for a few meters, then put it back in Park or Neutral and try rev it, its starts to hesitate again. The whole cycle is reproducible and it does not matter if the car is hot or cold.
I called the shop and they said it cannot be the autobox and so I began the journey to date.
The car already had a top end rebuild and the following items were new; Timing belt, water pump, spark plugs, leads, distributor cap, crank position sensor, fuel pump, coolant temp sensor.
Airflow meter, ECU and coil were swapped out one at a time but the car behaves exactly the same. TPS was checked with a multimeter and both idle position and WOT register perfectly.
Every electrical plug in the engine bay has been checked, sprayed with electrical contact cleaner, and wiggled while the car is running, but nothing to indicate they are at fault.
The bizarre thing is the car revs to redline in Park or Neutral, as soon as a gear is engaged and a car is driven only a few feet, it starts to act up even in Neutral or Park.
Does anyone know if there is any electrical anything related to the Auto Trans in an E30 that would cause this?
