So my '91 E30 318iS runs wonderfully most of the time. But in one drive she has a stutter at the same bit of road every time I drive it!
I can drive 30 miles from Aviemore down into Inverness no bother. On the way home there are a few big hills to climb at 70mph. About 2-3 miles after the final hill I'll always be sitting at 60mph due to average speed cameras. It's at this point the car stutters every trip and at no other time!
It feels like she's not getting fuel and with the clutch out she'll stall. She bucks and jerks in a most unhappy manner. But if I change down to 4th gear and get the revs up the fault almost totally vanishes. Still happens with a full tank of fuel.
I've tried new Motronic and fuel pump relays. Was thinking fuel pump but not sure.
Stock apart from clearing up "the mess under the intake". She idles perfectly as a result. Certain there's no vacuum leak. Not lacking power.
All help appreciated!
