im not gonna lie here...what the hell is a IAC and PCV valve?

 

Idle air control valve
Positive crankcase ventilation valve

 

IAC is a bypass valve that lets air get in without going through the throttle body. It allows the ECU to control the amount of air let in to the motor while the throttle blade is completely closed. Basically... it controls the idle.

PCV is a check valve that allows air to be sucked out of the crankcase to keep it ventilated of acidic fumes and nasty vapors of various sorts. The breather is on the other side of the engine and allows air to enter the crankcase to replace that which is sucked out through the PCV valve. The PCV will close if pressure hits it so you don't blow out seals and gaskets in the bottom end, like in the event of a backfire.

 

Not tryin to be an ***, but cleaning them does nothing, just a temporary fix if that...

 

hey... uh...

my car isnt running too great either...

any idea what the problem could be?

 

By looking at your sig.. You may need a new car.

 

it looks like you won the telephone pole chopping contest... that'd be where I'd start. Most cars dont' like being totalled.

 

WHAT!?!?!

she aint totaled

 

Not entirely true...I had the same problem slither had right around 40k or so...i'm now at 94,4xx and i haven't had a single problem so far...

 

oh... sorry. The caved in front end threw me. Tube chassis time.

 

You just got lucky....I cleaned mine and it lasted about 1500 miles and it acted up again, so I cleaned it and it didn't help, so I bought a new one....problem solved.

 

Random but this happened to my lawn mower today and now i cant finish the yard

 

is there gas in the tank?
