My 2001 V6 is acting really funny. After driving, once I put the car in park, the rpm shoots up between 1000-2000. While driving, the car wants to die all of a sudden, and I would have to put the car in neutral so I can step on the pedal to open up the throttle so I may be able to gain some power. But also, when I don't have to do that, I can just put the car in neutral and my rpms would shoot up to 1500 back up again. I'm really confused.
The only time my CEL illuminated is when I have to step on the pedal to open up the throttle whenever the car wants to die on the street. It has illuminated twice now.
Here are the DTCs:
P0122-Throttle Position Low Circuit
P0113-Intake Air Temperature Circuit High Input
P0190-Fuel Rail Pressure Censor Circuit Malfunction
A while back, the TPS was replaced and re-calibrated because I thought it was the cause of this high idling after performing some tests on the sensor. So why am I getting this DTC again?
In some cases where the rpm will be at about 1500 after I have parked, I'll disconnect the MAF/IAT and the rpm would drop to normal (<1000). I've also cleaned the MAF with CRCs MAF cleaner. Could it be the MAF/IAT?
Just last night, I went to the gas station and saw a trail of what I think was fuel on the ground. I went to smell it, but it was like a mixture of both oil/fuel.
The car has 177k miles, it's an automatic. Just recently, I replaced that little plastic bushing in the back of the engine which holds the rods for the intake runners. Going through all of that, I went ahead and replaced the upper intake plenum gasket (torqued in sequenced) and the valve cover gaskets. This thing has a new battery and a new fuel filter.
Thank you guys for all your help.
