96 sonoma ignition advance problem
I have a question for you.
I have a 96 sonoma, 4.3 4wd. I'm having a problem with it and i think it is a timing issue. It runs smooth, but it doesn't seem to have any power.
I hooked up my actron and it consistently shows an ignition advance of -6 to -30 degrees. What could cause the computer to retard the timing so much? The knock sensors, and ignition module are new, and i'm showing accurate temperature readings from my coolant temp sensor and air sensor.
The timing can not be manually adjusted, and the MIL light isn't on.
Please, any help/ideas would be greatly appreciated.
