LT5 Misfiring at All Speeds - ZR-1 Net Registry Forums

Big D · 07-30-2015

I got the swivel socket from NAPA and it works great getting the back two plugs out. It is easy with a swivel. Hope the plug is the problem.

I'm still chasing gremlins in mine. When I shoot back into the ECM, #6 injector pin is showing 86 k-ohms while the others are showing .97 - 1.0 m-ohms. Not sure if that makes a difference since I wasn't able to check to see if the injector is working; two person job and my assistant was working last weekend, one to turn over the car while I look down the injector housing to check for fuel spray.

Hopefully I will be able to check it this weekend.

By the way, anybody out there have a good schematic/diagram for the ECM, or know where I can get one? Would sure help in troubleshooting.
