Anyway to fix IACV???

[southside]

My car has had small stuff messin up lately im guessin since the person that had it b4 me really didnt give a shit about the car they didnt replace small stuff like sensors but my friend checked the code that being thrown and he said one code was tps and the other iacv which wont let me car rev over 2500 rpm is there anyway i can fix the iacv

[iEvo]

yea buy a new 1

[southside]

yea buy a new 1good one i had question for you did the evo in yo avatar is that the one u wrecked i seen them pics and was llike damn i hope that aint it

[allmotoronly]

yea buy a new one. the IACV wont keep you from revving over 2500 rpm though... it will make you idle really high. The TPS is probably the problem with it not revving high, since the ecu probably is getting a signal that says the throttle is closed when it is actually open, and it limits the fuel injectors.

btw, wtf is that ghetto rigged intake? you probably lost hp on that one. definitely did not smoothe the air flow any.

[allmotoronly]

and where is your pcv valve?

i am having similar problems i was reading a whole bunch of stuff last night about it and i would try pulling the iac and cleaning it with some MAF cleaner. ist about 6 bucks at any auto store jus my:2cents:

[EmminoDaGreat]

Probably the FITV on the bottom of the throttle body.

[speedminded]

Probably the FITV on the bottom of the throttle body.That won't make it top out at 2,500, just be a high and/or fluctuating idle...sounds like the ECU is in "limp/safemode" for some reason.

7 is TPS and 14 is IAC. Did you reset your ecu to see if will come off or if it will come back on? CEL I mean...

[southside]

7 is TPS and 14 is IAC. Did you reset your ecu to see if will come off or if it will come back on? CEL I mean...HOW DO YOU RESET it i took the battery cable off or watever and put it back on and it did nothin i have a check engine light but its been on since i bought the car

[speedminded]

HOW DO YOU RESET it i took the battery cable off or watever and put it back on and it did nothin i have a check engine light but its been on since i bought the carThe check engine light means it's throwing a code, the only two codes you have is 7 and 14?

[southside]

yes that is the only code i think maybe i counted wrong ive got one long blink 4shorts and 7 quick blinks

[1SOL2NV]

well do wut the EX owner didnt do .. Replace them sensors .. and call it a day ... junkyard will be your friend .. or jus buy them new

[southside]

yea i been getting around to gettin em all now but sensors arepretty expensive

[green91]

seeing how youve got a LS in an EF and both the TPS and IACV require wiring modifcations id start by checking the wiring.

[southside]

[allmotoronly]

HOW DO YOU RESET it i took the battery cable off or watever and put it back on and it did nothin i have a check engine light but its been on since i bought the car

you have to leave the positive cable unhooked for a while, maybe 5 minutes???

[1SOL2NV]

yea 5 minutes should be plenty ...

i wasnt being a smart ass, the sensors dont typically go bad and especially not at the same time asshole. so checking the wiring would be a good place to start. but good luck fixing it dickhead. youre obviously pretty smart

just a thought, but try switching the TPS and IACV plugs see if it does anything :2cents:

can't...tps is 3 wire and iacv is 2 wire plugs. good try though.
