ok so ive been having a code 22 and 31 for a wile now but fixed the problem. replaced the AFM and wiring harness codes gone and still idling like crap now the only code im getting is a 51. theres NO A/C system on the car at all. so retested TPS and it looks grate it reves up fine, pass 3000K but if i let go the gas the RPM drop and it dies.

No I took care of the code 51 sry I didn't update this.
Now I don't have any code poping up but still Scrapy idle and if I slowly raise the throttle it starts missing around 1000-2000 rpm but has no problem reving up past 2k no codes. It starts up fine

well right now it fires right up and idles good for about 1-2 min till it warms up and the idle should drop like normal well when it drop's thats when it starts bogging and wanting to die IAC catches it some times. NO CODES at all. TPS is good, timing is 10-12 DTC,

im thingking:

1. VAC leak, about to pressure test the whole system
2. reseting the TPS again. event thoe its god
3. IAC acting up when i clamp the air from the INTK pipe it dies havent checked the ohm yet

any other ideas or help.

forgot some info. if i try to push the gas pedal slowly it bogs and misses between 1000-2000RPM if i and more gas it will rev no problem past 2000K but if i rev it up like WOT from idle it revs up little hesitation and sputter at first but revs up no problem.

Unplug the TPS. If it runs better, that's your problem. Either its the wiring, TPS, or alignment. If it doesn't run any better, then look elsewhere. It sounds like a TPS to me.

I have to agree with Backlash. Similar problems were occurring to my 7m-gte and after Calibrating my TPS the car idles nicely at 650-700, never dies after high revs, and seems to have a little more pep. Also after Calibrating it I did have to adjust my Idle screw to get it to crank up and idle correctly.

well i made a vac tester out of pvc, i then installed it into the intake after the maf and applyed 12psi to the system and found alot of leaks two on the IC piping, one at the 3000-TB, and one by the brake master all got fixed. still no change in idle may have more leaks. One very small air leak at the IAC need to fix. funny part was i tryed looking for leaks with carb cleaner and didnt find any thing. Im still not sure if the IAC i good.

fyi: theres no egr, A/C system. aftermarket BOV but had it for a long time it could also be leaking.

yes i adjusted the TPS a few time and all the reading are good each time.

what was the last thing you did to the car before you got these 3 codes?
It sounds like you fixed something and caused something else to go wrong?

Also, have you checked the TPS according to TSRM? Have you done the tests to tell if your tps is bad? Sometimes it can be calibrated correctly but the tps itself is still bad

I know you just did a rebuild but try a compression test mayb? it make cars idle idle rough and run rough til about 2k rpms becuase when the rev goes it sorta smoothes it out.
Also, your timing is set correct is that right? Is it idling rough or misfiring at idle?
