Have you tried checking your MAP or TPS sensors?

robbys89

no havent done that. no cel lights. all i can do is check connections right? can they be cleaned or anything?

Was the distributor cap inspected or replaced? You might want to check the ignition timing with a timing gun.

it sounds like it is distributer related

the distributor cap is verly new. got it 3-4 months ago. i did once have a problem starting the car and i replaced the ICM along with the sensors from a sohc distributor (same internals) but in the end i was just me mixing up 3 and 4 spark leads but the car ran fine for say 3-4 months after then out of the blue this start happining

check and see if your dizzy wiring is tight in the dizzy plugs and see if the screw that holds the rotor in didn't back.

If it were me I'd check the cheap stuff first. Have you checked the fuel filter? My friend had a similar problem with his. Thought I'd just throw that in there.

Check all your vacuum lines and get some throttle body cleaner.
