I have an 88 2.3 that we race on an oval dirt track, we started with fuel injection and switched to carb that I did not like so we went back to fuel injection. Now the problem it won't run! we replaced the MAF sensor the computer, fuel pump, fuel filter, spark plugs. We have spark at the plug and coil but it won't fire. It started to run for us yesterday but after about twenty minutes in idle it will stall, also when it did run we couldn't rev it upbecause it would stall then. Please send any info or suggestions I will try anything right now.

same problem with another car we had, except we didnt change it over to carb. then back again.
honestly we still havent figured it out. the car has sat in the yard for a few months. my dad believes its a censor, relay or short.
sorry i cant be more help.

Thank you anyway. We are still replacing all the sensor hoping to find the right one.

88's didnt come with Mass Air

I was told that to, but this one did. I know the owner before me had the engine rebuilt at a shop but it was suppose to be the orginal. Could I be looking at a different motor then?

One more question where can I find the VIN on the motor itself so I can tell exactly what year that is? Because I know we changed a MAF on this engine.

well the motor you have is a split port motor which replaced the single port motor in i believe 90. it came with 105hp.

i had the same problem with my 2.3! i was told that it was the TPS (Throttle Positioning Sensor), yours could have went bad when you switched it back over to fuel-injection!

by the way, ur talkin about a oval car? would u happen to have any extra headers or cams that u could get rid of?

In california, they used MAF much earlier than the rest of the country, so you may have a california car. The 88 5.0's also got MAF in california.

Pull codes.

That will allow you to at least get an idea of its a sensor related issue.
