I have a 93 dodge d150 with a 318. While the vehical is in park it the idle bounces up and down. To the point it almost shuts off. Sometimes it does when I go to put it in reverse or drive. Once I'm in drive she will run good. It has a new coil pack, new distributer, new tps sensor, new plugs and wires. Is it possible that it is a timing issue?

Look in the Idle Air Control Area. IAC maybe acting up?

I agree with Bob!

Forgot to mention that, the idle control valve is brand new also.

RacerHog

What are the list of engine codes it is giving you?

demott128

If I remember correctly it was 12 23 55. I will double check once I get a chance

demott128

Just went and double checked, code is 12 22 55

So I looked up code 22, it's the coolent temp sensor. Now could that really make my truck idle rough in park?

RacerHog

The coolant sensors on those control the timing also in some cases.... Fix the codes and I think your problems will mostly go away...

Well I replaced the coolent temp sensor and the problem is still there. The connector doesn't look the best. It is a little loose fitting. Does anyone know where I can get a replacement connector? The wires look good.

RacerHog

CHeck with your local parts house and see it they can order that pigtail? As for the Coolant sensor, Dude, Thats just throwing parts at the thing to try to fix it !!!!! You need to test the Circuit and the values in a repair manual..

The truck sat for 8 years, so replacing sensors does not bother me. My local shop can't get the connectors.

Does it look like this one??????
