OP: IACV and FITV (depending on year model) are common source of problems. Before u spend $250 on a new one, take yours out, clean it with brake cleaner or similar item. let it dry completely. put it back on and see if that helps. Similarly, if you are close to a junkyard, finding a used one and cleaning it can be a solution that will cost u less than buying a new one. If all fails, then suck it up and get OEM one.

good luck! Tons of DIY on the net for how to replace/clean IACV or FITV causing idle surge

^^and its super easy.

unless your car is an auto its not compatible with his

they are free at most junk yards

or if you pay for them.. probably ten bucks.

They get dirty, especially if your car was/is running rich for some reason. Take it off and clean it with carb cleaner.

yea i cleaned it but car aint starting so i dont know if it runs lik crap? its been snowing and never got a chance to get to the car...i also got a code saying dat the intake air has an high input?

There's more than one IACV code. Which do you have? An IACV code does not necessarily indicate an IACV problem.

An IACV or IAT code would not prevent the engine from running. Is this a no-crank or no-start problem? If the starter cranks the engine, do you have spark and fuel?

metalmulisha87

the code said that i had a IACV failure...the car cranks over but no start i do got spark but not sure bout fuel havent gotten a chance to miss wit the car since its been snowing...could a bad Fuel pressure regualtor be a problem

Former User

Again, what was the specific CEL code? No CEL codes specifically indicate an IACV failure. Some indicate a problem in the IACV circuit (IACV, wires, or ECU) while others may indicate a bad IACV, vacuum leak, bad ECT/circuit, bad TPS/circuit, or a misadjusted idle speed.

Is spark bright white at all 4 spark plugs? Do you hear the fuel pump prime?

metalmulisha87

the code is: p1509 IAC Valve Circuit Failure...yea i got all 4 sparks and the fuel pump does prime...

Former User

Check whether the IACV plug gets battery voltage and also whether the IACV wires have a short or open. If all this is fine, then the ECU may be bad.

If spark is bright white and the fuel injectors spray fuel, then check the mechanical timing.

metalmulisha87

okay well do...u know how much a ECU runs for? but im thinkn of doin a swap?
