Recently I've been having an intermittent rough idle on cold starts. It would go away within seconds and run smooth. Now the problem is constant. Check engine light came on and gave me codes of 24, 34, 42 & 52. I did find the KS (afm) wire broke off of a crimp I did when I wired in the MAPECU. I wound those up together, cleared the ECU, and rechecked for codes just to get the same ones.
I was about to tear into all the wiring and check for continuity, rewire my rewired knock sensor again and the whole bit.
Today I stopped by a friends shop to borrow his leak down tester. Performed the test and cylinder #1 had 100% leakage!! Air was blowing past the intake valve cause I heard and felt it come from the throttle body. I quickly checked #6 because it was also at tdc on the compression stroke. 100% leakage in that one blowing past the intake valve, too. Timing belt must have jumped. I couldn't confirm this tonight because I was taking the family out for dinner and didn't want to get my hands too dirty.
I'll be getting into this the next coming days to keep you guys informed.
This is why it is important to do a LEAK DOWN TEST. I was going to be chasing my tail with troubleshooting all electrical sensors, harness, and ECU. I still might have an electrical issue, but I sure as hell have a mechanical one.
This is why I preach leak down test. It really should be the first thing down when having problems. Everybody having "rough" running problems need to do a leak down test.
I will add I run probably the cheapest, shittiest timing belt out there. It was new that I bought from another member that decided not to run it because he knew it probably wouldn't last. Go ahead guys, fire away.
