Wont hold idle, between idle and 1900 rpms,out of gear
Got a weird issue. Truck runs fine. But lately, when im idling i cant touch the gas and hold it under 1900 rpms. It instantly jumps up to 1900. Only works when im in drive or reverse then i can hold it at 700, 800, 900, etc.. any ideas? Im thinking throttle cable or something like that. I have a new iac on it, since i had a problem with it dieing randomly at idle.

I tested the old tps.
Idle- .33v
WOT-1.97
i also have a hughes intake with throttle body. I looked through there manual last night, since i also have a whistling after heavy throttle. The truck also does not have a warm up mode. If i start it cold in the morning it shoots up high then almost instantly drops to idle. Thats when i try to hold the idle at 1000 or so in cold weather to warm up faster but it wont let me, instead it goes to 2000rpms.

Maybe i tested the wrong wires. Manual isnt to helpful since it only says the middle wire is the feed to the pcm and everything else refers to using the DRB. So i probed the middle wire and the left wire as ground, towards the front. That was my reading on the 9v scale i used for my voltmeter. I replaced the sensor and still nothing.
