stalls in gear

[rein425]

cel came on , car stalls when put in gear, 98 duratec engine, autozone reads po113 error code, intake air temperature sensor circuit high imput, did test with digital meter and sensor test ok, any ideas what will cause that error code if sensor test good, and will that sensor being defective cause stall when put in gear

First of all, the digital volt meters can be decieving. They loop infinitely..
Start:
Clear Screen
Read Analog Data
Convert to Digital
Print to Screen
Wait - Could miss something.. The wait period is much long than the processing peroid.
Go to Start

So there might be a spike or something you're not seeing. I would re-test with a $10 analog volt meter.

That sensor doesn't explain the stalling, but... It does contribute to the air fuel mixture. But I don't know that much about the newer trucks (I love my simpler ODB-I systems) I am not sure if the engine is loosing so much power that the tranny just kills the motor.

I would however, recommend checking the plugs for a rich condition. This would indicate indefinately a bad sensor somewhere.

Grey deposits should be lean
minor grey should be about perfect
dry black powdery carbon should be rich
sludge on a 98 - shouldn't happen.
