The IAC was black... I just decided to replace it and cleaned the rest of
throttle body. The inital start afterwards was pretty fun with the idle at 2k
for a couple minutes. It seemed to work a little bit better and didnt seem to
stumble when I let off the gas. so that could be a good sign. It also started
a lot faster than it had been, although it didnt take long before.
The speedo and tach are still sluggish. Speedo especially, I know that I wasnt
doing 30 5 feet from the stop sign!! After stopping it dropped down. I didnt
get the battery checked. I put the meter on the battery and got 12.1 V, didnt
do any load tests... will leave that to AZ tomorrow if I can get by.
