[QUOTE="AfricanSnowOwl, post: 16486464, member: 168923"] I had some free time today, so I double checked a few different things. The computer was already pulled out and battery disconnected, so I decided to test wire continuity for pretty much every sensor. MAP, TPS, IAC, ECT, ACT, O2s, and the injectors I could get to all had good continuity from the sensor to computer connector. I did discover that the wires going to the A/C WOT relay were corroded to the point that some of the bare wires were touching each other. I fixed it to where the wires don't touch, but that didn't change anything with the idle. Re-verified timing @ 14 degrees. Tried changing it a little each way, but it seems to have the best vacuum reading at 14 degrees. The vacuum reading surges with the idle from 15" to about 14. This was with the idle at about 750 and surging. At some points the idle would come up on it's own to about 1000 and the vacuum would hold about 20" with no variations. Tried adjusting the TB set screw that changes the idle, but no luck. Idle either surges or ends up being way too high(1500+). [/QUOTE]
