coil pack help

7 July 2010
Nor Cal, So Cal and Puerto Rico
I think my car is having miss fire and i'm guessing it's due to fail coil pack. My car currently have back fire issues and losing power while accelerate. Can anyone tell me if that's the problem from the coil and where to find a 91 coil for the best price? thanks.
Have you pulled the error codes off the ECM? There are no specific "misfire" codes on a NA1 ECM, but there might be a stored code to lead you in the right direction. Many parts, bad gas/flow or a tune issue could cause your problem.
