ok so i havnt drivin my car in about 2 months, started it up yesterday it idled at liek 1500k then when it warmed up it would go up and down up and down from about 2 grand to a little under 1000. what could this be iacv, fitv, or map senser

 

I hate to tell the truth..but i have answered like 5 of these in the past week. Its more likely your fitv than anything. If not then clean your iacv,and if that doesnt work check your vacuum leaks and lastly check map sensor. Put money on the first two though.

 

yea i no i saw a lot of these to i searched but didnt see anyone with the same problem ill try to clean the iacv and the fitv thanks

 

I can save you time on that fitv. Just go to your car right now and take off your intake off of your throttle body. Once its off you should see a finger sized hole for your fitv on the left corner wall. Start up your car, and take a sock (i dont want to be responsible for you pinching your finger ) over your hand and plug the hole while its idling. If it purrs like a kitten then take off your fitv and tighten it. If it doesnt then search another problem i listed.

 

By the way what year is your car and if you have a motorswap in it tell me.
