325i stalling problem

[bethbdm]

My 94 325i has a stalling problem that no one knows how to fix. No codes are being set. Will stall without warning, usually making a left turn or going up hills to the left. Dealer said needs new tranny - but I think it is fuel or electrical. Anyone come across this problem? HELP!

fuel pump? Injectors may be? an easy start would be to change sparks and get a new fuel filter. Then go from there. If car runs in straight accordingly, then the tranny is fine.

Had the injectors cleaned and a relay replaced - also a sensor replaced. Dealer said it was fixed, then as I drove last week it stalled again. Came to a light, made a left turn - it died. No warning, no hesitation - just stalled! I'm at my wits end! Been back to the dealer 3 or 4 times now.

I just bought my 1994 325i from a private party and they had a similar problem. What they found was that the gas cap wasn't closed tightly and some water got in the gas tank when washing the car with a pressure washer causing it to stall as well. Just another thought...

Thanks for the reply's. I'll try anything at this point. One other thing that was done was the idler control valve was cleaned out...but to no avail...still stalls!

does it sputter and stall or does it stall as if you just dropped the clutch in 5th gear at idle (BAM dead stall!)

[bethbdm]

Its an automatic - but it just stalls - no warning, just BAM - dead. It will restart, but once you hit the gas, it dies again.

It may be airflow sensor problem.

ICV.. clean it or replace it.. same shit was happening to me and someone posted a FAQ on how to clean it.. did it and it hasn't happened since..

It could be the mass airflow sensor, but the computer would be reading a code for that failure. It the computer's not reading any faults, it's most likely a loose or cracked vacuum hose. My airflow hose was just barely off the rim of the airflow sensor, and whenever I started the car, it would die. If the computer's not reading any faults though, it's probably not a failure of anything. Check your fuel injectors for leaks, and check all of your vacuum hoses.

A newbie here...but i got worse than that...95% its electrical...check the transmission/engine mounts if they're too loose...my car will stall if you step on the breaks or slows down to make a turn or even on a stop light...its kinda scary coz what if a 20-footer is behind you and the engine just died... ghead

...other place to check are the sensors...t-stat, engine speed and grounds...

goodluck!
