I have a 1987 325i, 250K+ miles. Car runs very well but have recently had a new issue where there is a hesitation while driving or idleing. The check engine light always flickers when this happens. The car has stalled if this happens when idleing. Seems like there is an interruption in gas to the engine or water in the gasoline. What could cause this and how can it be fixed?

Thanks for the help.

change the fuel filter. also clean the AFM, ICV, and check the connections. but if worst comes to worst, youll be replacing the fuel pump(s)

i replaced the icv and fuel filter on mine and it runs perfectley now, it had the same problem even though it only is a four cylinder, same thing would happen.

check if your engine is fully warmed up.
