Forgot to mention, if you do reset idle speed, the part of Plumcrazy's procedure involving the engine computer and the screw at the TB, you need to recheck the TPS. Turning the screw changes the throttle blade position. The idle speed resetting may not be necessary, though you still need to...
Plumcrazy has it covered. I would do the TPS first though since you don't need the engine to run. Having the TPS cal'd. before the IAC may make it easier to maintain idle for IAC adj. Also, measure the IAC motor and make sure the distance from the shoulder of the housing to the end of the...
I would first focus on the TB. If this has never been cleaned, I would start here.
It is not difficult to remove, just a little time consuming. This is from memory so bear with...
MAKE SURE YOU HAVE REPLACEMENT GASKETS and coolant. see #9
1. Drain about 2 quarts of coolant. This should be...
Normal driving around 20. But, when I drove from California to Maryland I averaged 31. I did not believe it until I added up my receipts. I was driving VERY conservatively.The first week I bought the car I probably got aroung 8.
The best way to clean the T.B. is to remove it from the car. This allows you to remove the Idle Air passage cover on the bottom of the T.B. and clean the Idle Air Motor port.
Also, by removing it you can access the from the rear of it as well. You can also check the plenum.
If it still...
i would not disconnect the canisters, they are necessary. the vacuum lines from the air diverter valves can be removed with no prob. The exhaust manifold pipes should have check valves on them. You can take hose them correct diameter about 3 inches long and put it on the valve, then palce a...
How did you test the spark. For HEI, you MUST ground the plug. If not, you can ruin the module.
Loosen distributor cap and move cap CCW. This will advance timing. Only move cap about 1/2 inch at a time. Each time try to start engine. Once you can start it. Shut down and connect timing light...
Make sure your TPS is properly adjusted. .54v at idle (+/- .075v).
Check base timing. I believe 6 deg BTDC.
MAF. Disconnect MAF, be sure to keep wire from touching belt, and start car. If consition changes, prob. MAF. Turn off ignition before reconnecting.
Good luck.
