Mein Auto: e36 m3
Hi,
I have a similar issue. The car had a few niggles when I bought it including a bad petrol (gas) smell, very lumpy idle, rough running when cold on a constant throttle.
Took it to a good 'M' specialist to give it a good looking over who cured the petrol smell (leaky fuel pipe in engine bay) and the lumpy idle (bung/rubber cover missing off throttle body) and all seemed well.
After driving it in town in heavy traffic in hot weather the car started being hesitant on constant throttle on the motorway and even a bit when accelerating.
When it had been to the specialist the only code that came up was because of the bung missing. Vanos was fine. New fuel filter fitted. Car drives fine otherwise. Happily pulls to 7k on a daily basis

Has anyone got any ideas before I go through the plugs/leads/coil packs route?

Many thanks in advance.

Oh, it's an E36 M3 3.0L '94.
