My 92 325 Runns Bad

[Lil Grease Ball]

I have a 92 325i Sedan with the M50 and its automatic. I bought the car in october and it ran bad then it was involved in a wreck a week after i got it, (more like i buldozed a ford aspire with it). It will sit and lope at idle, is sluggish (a cavalier is faster) gets like 10 mpg on 92 octane, sometimes starts hard sometimes. I know the oxygen sensor is stock, (there is a 186K on the car) It has a cold air intake with a brand new air filter and an aftermarket muffler when I bought it the guy told me it had just had coils and plugs put on it. The check engine light comes and off but I dont have a scanner to pull codes on it. Please help me out

Thats pretty bad. I got the same car with 190k. Stock everyhting,24mpg on 89octane. It runs ok for its age and lack of care.

coils were changed yaers ago. Same with the plugs.
O2 sensor maybe original. I just got ther car a few months ago.

Did your car run ok before the wreck?

I would check to see if everything is hooked up.
Check all the plugs.
Check the intake boots and connections.

Also do you get a check engine light or the "CHECK" light. The "CHECK" lights works with the OBC(multi info display) for non engine problems.

Find an independent BMW shop and have them diagnose the problem(s). Or purchase a Peak research tool and pull the codes yourself, if you do this you aren't guaranteed to find all the problems. And stop crashing cars! :mad

If it's a 92', can't he use the "pedal trick"?

[Lil Grease Ball]

is there a bleed procedure on the cooling system to work the air out bc my radiator is cold, hoses hot, gauge in the red and no heat

no mean to hijack, but afterall how in the hell do you check for bad coils?

Test resistance with a multimeter. Although, I saw someone on here who said that's not necessarily a reliable test.

Run some SeaFoam thru it :)

Go to bimmerdiy.com They will have most of your answers.

You can read your code with the pedal trick. 1+4 or 5 times real quick? I forgot but its on the diy site. It took me about 4 tries to get the timing down right on flooring the gas pedal to get the code to start flashing.
