i have a 98 concorde 3.2l, i have a #6 cly.i have swaped plugs and coils,replaced injector i have no vacuum leak the compression is good across all the clys any help would be appreciated(the misfire diminishes when hot)

 

well, without connecting my diagnostic equipment and physically analyzing the data I'd recover, then it's a total shot in the dark. Sounds like you already threw a bunch of parts at it. Glad to hear you did a compression test, but you can still have a compression issue that only shows up running (like a broken valve spring)

 

Thanks.please discribe how to do a running compression test
