Hi I wonder if someone might have an input. Small issue with a 95 Mini Cooper SPI. It has no throttle position sensor near the pedal.

Vacuum line are all good and it’s idling well and driving well.

When cruising it has a small surge or jerking but that doesn’t happen all the time.

I’m wondering if it could be fuel putting too much in and therefore surfing or an electrical issue with perhaps the relay. It’s only just happened so not bad time to diagnose yet - wondered if anyone else had the same.
