I adjusted the timing as far as the dizzy would let me... no luck.
Then I took the dizzy off!! I don't know why. Now I have to figure out how to put it back in the right way
I will look for vac leaks again, but yesterday I found none.
I am thinking either the distributor needs to be replaced, or the cam needs a slight adjustment.
Does anyone know if I can adjust the cam from the dizzy side? or do I have to take the timing belt off?
I haven't actually driven the car, I just rev'd it up and held the pedal at different RPMs. It sounded pretty smooth and even all around; except idle.
No. You can't adjust the cam except by moving the belt on the gear. Doesn't sound like that's your problem anyway, though.
The distributor will only go one way. Look at the slot in the end of the camshaft and the corresponding tangs on the distributor. See that they are off-center? Got it? Good.

Check for problems with the IAC (idle air control). They're notoriously hinky until all the air is bled from the cooling system anyway. The way it functions is by bypassing air around the throttle plate, giving the same effect as partially opening the throttle. The ECU sees 'lean' from the o2 sensor, adds fuel=bingo. That's a big oversimplification but you get the idea.
Test it: Take off the intake arm and look for a port in in the throttle body in front of the butterfly. With the engine cold, running (IAC open) you should feel a strong vacuum there. You may even choke the engine down by plugging it with your finger. As the engine warms up, that pull should be less and less, but never completely shut.
Thanks for the tip bam,
I am starting to think that between the system having air in it, and the leak on the t-stat housing... there my problem lies.
I'll be able to take a good look at it Sat. Thanks for the tips...
I haven't bled any systems at all... I guess I didn't realize it could have any real effect on idle. Oh, and NO engine codes as of now.
She doesn't even try to idle... It will run smooth with my foot on the gas, but no idle.
I've tried adjusting the timing at the distributor, and I tried playing with the idle. No Luck
I am still running through some of the suggestions yall given; like IAC and dizzy rotor, but I thought hearing it for yourself might help.
I am trying to read through bleeding the coolant system now.
I will try tomorrow. The car will run at any RPM I want it to, using the gas pedal! It will even run way below idle if I ease the throttle that low. But as soon as I take my foot off, it cuts out.
The thing is, it's hard to find anything about the AIC in the manual... heck the manual calls it the EACV.
I really don't know what all I can do to troubleshoot it?
I'll search HT in the morning.
thanks

EACV- same thing. Idle Air Control is just a generic term, sorry.
You were right on bam-bam!
The Electronic Air Control Valve was crusted and clogged with the same funk that was on my water pump. I took the it off, took it apart and cleaned it with brake cleaner. It fired right up and idled perfect after that!
This was the problem; All that corrosion and rust from the water pump was clogging the Electronic Air Control valve (EACV or IAC). bam-bam called it. He told me three times to check it out... it finally sunk in. =]
Now the hard part is over... I noticed the car vibrates at idle. Seems like it could idle a lil higher so I'll have to play with that. I've also noticed a "clunk" when I shift sometimes. I think I have a busted mounted somewhere in the drivetrain. I'll have to track that down too.

Any flash codes from the ECU?

If you hold the throttle cracked open, will it idle where it should (750rpms)?
