Sputtering / Loss Of Power

[streetdreams]

Ok so my car was idleing like crap and the check engine light was on the code was saying the o2 sensor needed to be replaced, which I did and it still idledl funny.

A mechanic suggested disconecting the maf sensor and seeing what happened. I unpluged it and the car no longer sputtered. I left it like that for a while, then decided to plug it back in because the engine light being on was bugging me. Anyhow the car (92 325i) has a loss of power now either with the maf sensor plugged in or not. I think it might have fouled the plugs from running the car with the maf sensor unplugged.

So now it idles fine with the maf sensor unplugged but it has hardly any power.

What do you guys think I should do in steps to figure this out?

bmwcrazy should've said "Clean the MAF very carefully".
MAF essentially consists of a thin wire sonsor. You should
handle the MAF very carefully. It's very easy to destroy
the MAF.

If you are trying to save money, try the route of cleaning the MAF.
If you just want to take care of the problem once and for all, buy a new MAF.

Good Luck

THIS SOUNDS EXACTLY like what is wrong is my 93 318 IS. Yesterday I just picked up spark plugs, and an 02 sensor. I'll be trying these tonight... But now Im starting to think I should be cleaning my MAF. Does anyone have a good DIY, or reference guide for this? I can't find one in the FAQ.

Is it fairly easy?

Cheers,

Just rip the MAF out and spray denatured alcohol on it and let it dry. It's like 2 screwson the metal belts that hold it in that's it!

Try drugstores like Walgreens or Osco.
