Fault in YOUR 5.0 ?IAT/ACT Intake Air Temperature/Air Charge Temperature Sensor
Bringing my car back for a weird power and RPM loss when warm that has occurred every since I owned the car, the tuner discovered the IAT/ACT was reading WAY WARMER Air than it should be,
/ being located in the stock position intake manifold.
It has been relocated Yesterday to the CAI Pipe away from the engine and reads the same as the outside air temp now.
Any feedback on this?, my car pulls alot better and feels different cold and hot, same sensor different location.

You can leave the old one in the old hole to stay sealed, or buy 1/2 plumbing nut from home depot and screw it in, take the sensor with you if you want to match
all you did was trick the ecm into putting more fuel into your car... the tuner could have just fattened up your fuel tables a tad and you would have had the same results
the ACT reads temp in the manifold, when an engine runs, it makes heat. Therefor, you inherently get warmer air temps..
And for those of you whom are reading this thread. I would take all of AODE08's advice with a grain of salt... he's supposedly an ASE tech, but when he couldn't get his flexplate bolted on, he enlarged the holes to get it to fit... then wondered why his car was shaking while running.
