Random missfire ?

cruzman14 · Jul 24, 2016

I've got.a random miss fire on my 97 k1500 305 vortec. Seems to be cylinder # 2 and 4. I've replaced coil, distributor, fuel injection spider, compression good on all cylinders and good vacuum and fuel pressure. I can't figure it out. Any ideas would be appreciated.

This may not apply to your Vortec, but here goes:
My 6.0 2001 had a random multiple misfires code, time after time, and after lots of head scratching and plenty of parts, I did a crank relearn with a Tech 2, and it all sorted out. And allowed the TCC to operate too. Tech 2's are on fleabay, like my one, and a tool well worth the money I think.
Hope this helps! Best, Paul in UK
