Engine Performance problem
1991 Dodge Caravan 4 cyl Front Wheel Drive Automatic
----------------------------------------------------------------
I bought this caravan for cheap, because it would not run. It would try to start, but wouldn't quite make it. I brought it home, drained out all the old gas, replaced the fuel pump assembly, fuel filter, pressure control unit and finally the throttle body fuel injector. It will start, but won't keep running unless you continually pump the accelerator. As soon as you quit pumping,it dies. Can you tell me what might be the problem? I have used up what few brain cells i had left. Thanks a million

Hi caliber51
Need to check TPS Throttle Position Sensor located on throttle body. Remove connector get an ohm meter check resistance between terminal 3 and 1 must be 3500 to 6500 ohms if not replace.
If good then Check resistance between #3 and #2 operate throttle resistance should vary smoothly throughout throttle movement if not replace.
Let me know
