Timing issue
Ok guys, I keep reading how to unplug the EST wire near the blower motor to set the timing. I can not find this wire. The lable under my hood says to unplug the 4 wire connector. There is a 4 wire connector that runs to the dist behind the drivers side head. This is what I unplugged to set timing. I set it at 0 degrees unplugged. It appears to be about 16 degrees when plugged back in. Does this sound right?

the est bypass wire is for the fuel injected cars ONLY because if you pull the 4 wire connector, the engine dies because the ecm no longer has a reference pulse. Just make sure the engine idle speed is whats specified. The timing will jump when its pluged back in because the computer will agian be giving it advance.
