I have 1991 Isuzu Rodeo with a 3.1L V6 TBI. The car will start but almost immediately stalls. The injectors are pushing fuel. In order to keep it running, I have to give it gas. I have tested the throttle position sensor, map sensor, idle air. They are all fine. Also the fuel pump is working properly. I also replaced the pick up coil. Even after all this, it continues to run the same way. I am out of ideas and could use some thoughts as to what else to look at.

Hi stacey143,

Is the Check Engine Lamp indicating?

Was any repairs performed prior to this occurring?

Did you check for vacuum leakages at the intake manifold?

Get the trouble code retrieved to find out what is causing the CEL to flash.
