car ran like a dream put gas in one night & next morning when i started it it stalled right away it will run only if i hold the revs quite high, i changed the fuel filter & pump, throttle position sensor, injector thing (small round piece on top of carb), did electrical bypass & it still stalled, was told it didnt have a computer to get trouble codes, would the regulator have anything to do with this problem, any suggestions would be really appreciated as i cant really afford to put it in a shop

It sounds like you may have an inoperative AIS (Automatic Idle Speed) motor in the throttle body. The computer CAN be scanned on this vehicle with the proper connector. It's a black, 6 wire connector near the driver's side shock tower. Before you put anymore parts on it, I would take it to a trustworthy shop that specializes in drive-ability issues. They can test the operation of the AIS with a scan tool and see if it is working properly. Note, you may want to leave the vehicle overnight and have the AIS motor tested "cold" as I have seen these AIS motors work OK when warm, and not work when cold. Another common issue with idle speed on these vehicles is the wiring harness to the throttle body (at the rear side of the valve cover) can chaff through and break or "short" together, causing the AIS to be inoperative. Even if the wires are just badly oil soaked, they should be replaced. Another possibility is the EGR Valve (if equipped) could be stuck open and cause this same problem. So as I stated before, you need to have the computer scanned for any fault codes, and go from there. This vehicle has 2 computers that allow the vehicle to run. The "Control Module", which is where the sensor information is sent, and is mounted behind the passenger side kick panel. And, the "Power Module", which operates the high voltage components of the fuel system. This is mounted on the drivers' side inner fender, behind the battery.

it could be a bad throttle positioning sensor, or a bad MAP sensor. With that car, you can read the basic codes by turning the key off and on three times, and counting the flashes the check engine light. A better solution is to have a real computer scan done, some auto parts places will do the scan for free!

if its fuel injected,then its got a computer.does your check engine come on,if it does,take it to auto zone and have them run a code check on it.it could be the idle air control,or a throttle position sensor.also check the cat.,it could be half plugged up.if its got a bad cat,then it wont stay running.
