So....I have been having an idle issue for a while now, the car would run and rev all the way up, but it had bad throttle responce. the idle would search, and the car would sometimes die. it sounded like the maf but when you unplugged the maf the car would run worse, to i ruled that out.

Through the use of a multimeter, i traced the problem back to the TPS. I replaced the tps, and adjusted it to the proper specs. but when i started my car it ran like ****. Just for the fun of it, i unplugged my maf. the car ran almost perfactly! (just sounded like it had a revlimiter at 2500, which is normal for a car with no maf)

(car has tuned ecu, inj and r32 maf)

P.S. I have all the stock parts (inj, ecu, maf) and when put thoes parts on, the car does the exact same thing!

Please dont kill me for another maf question, i really searched on this one! i think its the maf, but the situation is really odd.

any ideas?

Ya, i did unplug it. seemed not to make much of a difference. maybe ran a little worse.

wzntha, where in LA are u located? i dont know anyone that owns an SR., Im trying to find someone near me in order to check my stock MAF and make shure it works.
