Misfire at cruise, popping/afterfire at 3000RPM
Quick update: I do have another thread started about this engine, because I thought I was going to pull/rebuild it. Turns out that the lifters had bled down, and that's why the rockers looked to be all the same angle. I removed the intake, and the cam is fine. So, I'm not going to rebuild the engine just yet.
I did, however, send the heads to the shop to get the springs and retainers correct. They're also going to look at the seats and guides.
While inspecting the harness prior to doing some electrical troubleshooting, I noticed it was in such bad shape that I'm surprised I haven't had even more issues than I already do. I found a new replacement, as well as a new spare ECU harness that I'll install.
