Need your advice on my 318, Since I bought this car its been a headache, I cannot exactly Pinpoint the fault.
1 time i was able to make things better, and in my happines i tied to wash the engine with stp degreaser. and water it after. all was well until when im running on the road, the engine seems to be dying when I accelerate, and when in neutral, its ok.
after reading some similar incident in this forum, i change coil pack ang plugs,
but still its the same. it feels like a vacuum leak but all my hoses are tight,
believe it or not it could be the maf i had all sorts of stuff happen car forgot how to drive littery after 9 months of it with techs and mechs haveing a look and charging like a basted bmw cleaned out the the maf till i can get the $1100 to fix it try looking at this
it should be BMW cleaned mine ( its a 99 316)just make sure you use the rite product at first i was using throttle and carb cleaner and i didn't take the part out as i didn't have a screw driver tip to fit it didn't do any good in the assembly but in the cleaning video he says a product name but i didn't catch it
You can clean it good with a high alcohol based solution like Isopropyl, put the MAF in a sealable bag or plastic box and let it soak for a while... DO NOT BE TEMPTED to manually clean it with a brush or even put your fingers in there as it may trash the MAF, it's very sensitive...
Give it a shake or three in the solution too... Watch that sludge come off LOL.
Afterwards, let it dry naturally and re-install, Job Done...
Eso es todo! Please press the "REP" button if you are happy with your response/answer...
Ok so you had this problem after washing the motor? did you get the fuse box wet? and did you spray water on the passenger side of the firewall? this where you DME is located. check your fuse box to make sure there isn't any water in your relay areas and your fuses. Also go over your injectors fuel pump and fuel filter. It sounds like you not getting any gas to the motor when under load and from a far it is difficult to determine that it was caused by water or a crazy coincidence.

Why sorry Dabsy, youre very helpful , all of you I mean, and i need more suggestions guys.
The BMW mechanic came last night although he did not bring any computer, he said letys replace first the Cramkshaft position sensor, we also check the the coputer box and its all dry within, fuses are all ok. but Ill blower them later and check again 1 by one.
for now the car can idle roughly with a few spur of backfirem, but the engine dont die down, it keeps idling, so I will look for a cps again and mount it.
