My 325i sometimes jerks along on part throttle, or when coasting. It is worse when cold, but when you nail it along its fine. I have changed plugs and leads already.... any advice appreciated lots

I had the same symptoms on my 320i.

Injection rail is usually the problem as water tends to gather there. However it turned out by trial and error that the ecu was fcuked!
