It is most likely the FITV. If so, I can come fix your problem for you in a few minutes. PM me.

 

i checked all sensors and it still does the same thing.

 

Your FITV needs to be taken apart and tightened back down. Take off your intake tube so you can see inside your throttlebody. You will see 2 holes on the inside of the throttlebody. Put your finger over the bottom hole and see if it fixes your problem. If so, than your FITV needs to be taken apart and tightened.

 

bravo! i see that someone else has figured this trick out as well

 

haha yeah. It is such a common problem. I don't know why most people don't know about it.

 

would that cause it bog when i full pedal it.

 

Not usually, no.

 

that could be a TPS problem.

 

can ya talk some more about that throttle body trick, and the meaning of different sensors like the "FITV" etc...
i would like to learn more about that..


thanx

 

Fast idle thermo valve has a wax pellet in it that melts when the coolant reaches a certain temp, and then allows the valve to move closed when vacuum is applied. It's an idle air control valve of sorts that allows extra air to bypass the throttle plate when the engine is cold. Obviously the wax solidifies when the temp goes back below whatever threshold, so it's self resetting. Pretty clever, very crude though.
