well my front 3 cylinders arent getting any spark but fuel yes.
only the rear 3 cylinders are combusting.

check engine light on and opulls a oxygen sensor code only since the mixture must be rich.

change cap and rotor?

how much do they go for ?
any other imput please

Thanks

still need help please

you could have a crank sensor problem, or a computer problem. A cap and rotor would run about 36.00 cnd for rotor list and 167.00 cnd for cap list.

check the cap and rotor first.

I changed the cap and rotor already and notim thinking its the crank angle sensor..does this problem happen where the front 3 cylinders go out and only the rear fire up??

Thank You
Peter

usaly the crank sensor would only work or not work not intermitent on 3 cylinders. If you know someone in your area that has the same car try there computer thats probly your problem. If not could be a air mass sensor but they don't usally go bad.

Hope this helps.

Check your post in the General Maintenance section.

On my car the fuel injector just wanst clipped on all the way when i worked on it once. Check all the simple stuff first!

Ok Thank You so much and where is the DME located?? engine bay or interior?

Thanks
I just called my local BMW salvage yard and the crank angle sensor is 25 used or 60 brand new

Well where si the DME again?

Thank You
