Coil question
I am detecting a minor misfire underload. My injectors have been changed in the past I changed the pumps, plugs and wires just 2k miles ago. I am thinking I have a coil issue sense the coils seem to be original. my car is a 91 with 77k on the clock.
I was wondering what coil people go with my car is stock with the exception of headers and flowmaster exhaust Dave |

Re: Coil question
Don't use Accel, had two on the 91 I am working on short out and blow out a 20 amp fuse; I have had no issues with generics from Autozone or O Reillys

There is another coil that externally looks identical to the correct one for the ZR-1 & it fits all sorts of other vehicles. However, it has a different PN than the ZR-1 specific coil. I can't cite specs right off hand, but I recall that there is a difference in windings/resistance. FWIW, it's always been about 1/2 the price of the ZR-1 specific coil..... just like the one referenced in the link. I would think long & hard before buying this coil for an LT5, especially since the seller does not state the GM PN in the auction.

Re: Coil question
I had an OEM coil die at less than 8000 miles so might want to rethink that one. I'm running MSDs.
