Starting from the beginning on the newest member of the family, just bought a 93 z28 and have a couple codes that i was wondering about.. i have a 41 and 42 code.. points to the Ignition Control Module correct?

 

Hi, Welcome... This is what I have for those codes. You might do the ICM cooling mod if youre going to swap in a new ICM. That and many other good How To's in here,,, 4th Gen LT1 F-Body Tech Aids

41 - Ignition control circuit, open
42 - Ignition control circuit, short or grounded

 

Thanks for that... might do that mod for mine
