94 2.3l Timing right?
Trucks been running real bad, wont stay running when cold. Found cylinder 2 & 3 on exhaust side wasnt firing. Found out bad ICM, changed. replaced coolant sensor and IAC valve. Better, but stil runs bad.
Decided to test timing, this is what I found.
I disco'd the SPOUT connector ( I think, I followed the pink wire in the diagram from book and found a single connector, with 2 pink wires, had a single plastic plug)
I then checked the timing with the light, and the plastic guide was labelled BTC---->20--->10--->TC
The mark was showing halfway between 10 and 20. While idling, the engine would "stutter" and the line would drop down to TC
With the SPOUT in, it was idling @ 20
