Hi. I'm a carguy from Norway.
Is there anyone who can help me with a problem I have on a 95 LT1.
I use PSI wiring for this setup.
I was driving and suddently it started to run very rough with load. It seemed like it only ran on 5 or 6 cylinders. I looked at the spark plugs, and 2 on each side were almost white and the other two was really black. I changed the spark plugs and the problem seemed solved, but I still have a little rough idle. Then I hooked TunerPro up to see I could see any problems. I found that both the O2 sensors is jumping up and down all the time. I changed the sensors but it's still the same.
I have attached a log-file.
Any ideas about what this could be??
