Finally got 'er fired up and running today! Hot damn!!!
Ron, I did what you suggested yesterday: pulled the plugs (coated w/carbon but cleaned up well), spun the engine (no sign of fuel, but it had been several days since flooding), reinstalled the plugs and reassembled the induction system. You have to remove the intercooler and bypass valve body to get to the plugs on the left side (what a PIA). There's always that ONE vacumn hose you left off when everything is put back together!
Finished up Sat night and tried to start......nothing. So I decided to come down with hayfever and gave a rest overnight. Sunday morning, I pulled the fuel pump relays, and the air sensor switch delayed relay (in the engine compartment) and checked with a volt meter. I think my air sensor relay is weak because it rattles when shaken and I can get resistance between varying pins after shaking. Guess I'll replace that soon.
Anyway, I put all relays back in and tried it just for grins. I started, but didn't want to idle at first. Kept the pedal down to idle at around 1000 rpm until it decided to idle at around 300 rpm. It slowly increased speed with some surging to normal idle at around 900 rpm at operating temp.
Shut it down and changed the oil to get rid of fuel contaminated oil. I'm trying the Valvoline VR1 Racing (dino) oil 20W-50 this time around.
Started back up and backed her out of the garage for the first time in about 8 wks and let her warm up. Idle stabilized at around 1000 rpm and took off after adjusting oil level.
She ran fine and noticably quieter with the replacement bypass valve body which came off an '89 when on boost. My old bypass valve must have needed resealing. The only thing I noticed was the idle dropped periodically at stoplights, but bounced back to 1000.
I stopped and added some Techron (2 pints) and filled up the gas tank. After returning home, turning off, then restarting, the idle did not want to stabilized unless I gave it some gas to keep the revs up for a moment or two.
So, my problem seems to be uneven and low idle at cold and warm startup. I checked the auxiliary air regulator resistance which was 24 ohms. Is this too low as the spec is about 33 ohms? I pulled the hose off the AAR to observe the sliding plate. It seems that it closes off too much since when I pulled the plate open slightly, the idle rose and stabilized. Is this a common problem? The other possibility is maybe the car is running too rich?
