hi, like i posted last week i block-off the fitv and replace the iacv (used) and the car went to 800-850rpm (22-23 in hg) at idle. This wensday we going out
to make some pulls all fine, but back in house let the car cooling down in idle
and the surge come again 1k to 1.5K spend one can of carb. cleaner no leaks.
When i go to put the car in the garage turn on the a/c and the car sit at 900rpm. Po6 chipped ecu no code, maybe TPS went bad or buy a brand new iacv.

any help thanks

ok. if unplug the tps stop bouncing and stay at 1.4k so is not the tps anyway
i go to measure it.

update: Tps measure .45 and 4.4 wot. In some thread i read about cracked
intake manifolds it's comonly in b16's? maybe is time to remove mine
to take a look.

why did you remove the fitv? put it back on and tighten the white cap inside of it.
Chipped for a ls-v?

carlos8

cause the plastic on the plunger was broken, but with the temps here in P.R.
i no have any cold start prob. when i find another i put it on but my throttle is obd2 and my intake is p61 it's diferent to all b16.

And yes the car was dyno tuned and it's workin great till last week.
