i got my motor started its an s14 sr20 vvt in an s13. the problem is when it first starts it revs by itself to about 2500 and after 30 seconds it slowly drops and sputters to death. when i give it throttle it wont go past 2500. i figured it a mafs problem but could it also be a bad tps? i think its the tps because it revs up by itself. any thoughts?
