Cold Start Problem and Un-even Idle...

[Ednamillion]

Just had timing and drive belts changed, water pump and coolant (blue) temp & temp sender sensors replaced. Thermostat changed.

Looks like cold starting is a problem now. Starts but foot off the throttle (say changing through (auto) gears) engine stalls. And, either at idle or when driving, there's an unevenness to the engine which wasn't there before. When driving you'd almost feel the slightest miss or kick-back through the peddle every 5 or 10 seconds....any thoughts?

What year and engine is the car pal?

Shag it! Sorry, thought I had it in a sig or something...

'92 M40 (318i) auto....

Just to close this out....It looks like I had a dislodged IACV connector (likely cold start problem) and a couple of my leads needed a bit of a clean (and likely replacement) solving the hesitancy we were feeling while driving.

Driving fine now.
