Went to see a swapped Neon, 1 small intermittent problem?

Went to see the car once, no problem whatsoever, car started fine etc... Apart from some cosmetic imperfections the car is clean.

Second time I go see it, the car starts and stalls immediately, like it wasn't getting gas. If you gave the car gas when starting it, it ran until you let go of the gas.

The seller happened to know the problem, told me it rarely happened and that is was on very humid days only. The guy seemed to know what he was doing, removed a connector, took a needle and "scratched" the pins on both connections to make sure there was a good connection, blowed in both connections and replaced the connector. The car started fine and we went for a test drive.

Now the connector in question, from what I saw, had 2 pins and seemed to be connected on top of the throttle body and the wires seemed short.

The thing I want to be sure about is if that connector is the TPS one and would it cause the car to start and stall immediately if there was a bad connection? ModernPerformance sells both the rewire kit and the sensor in question and if that fix the problem, I'll buy them.

Thanks

Ya the TPS or wiring goes bad alot for some reason. That being bad would deff allow it to stall.

I have only heard the TPS problem causing the car to idle high or hold revs, never knew it could make the car stall. Could also be the Idle Air Controller on the TB.

TPS has three wires, IAC has two wires....it was probably the IAC motor.

The inside of the connector looked a lot like that. But that's a fuel injector one from RSAutoSports

Just checked on Modern and found the IAC rewire

Can't see the inside of the connector but it's almost exactly like the fuel injector connector above so I suppose this must be it..

Tip the iac connector looks similar to that.

I like how all the Mopar connector repair kits use the same blue wire.

For what you pay for them, they could at least use the proper color code. The injectors I can sort of understand, because it would be nearly impossible to know how many are going to be the most common failures. But they could at least make the common side the correct color.

late model 02-05 use the 2 wire connector which ends up being the same connector as the injector. The 00 and earlier connector is a 4 wire unit....

Ya I had a TPS fail and it would stall out
