Hey everyone, I have a 2003 Acura TL. My car has been sitting out on my drive way for the past 4 months now because I dont have money for a new transmission. So I turn it on sometimes and I always hear the engine reving up and down. Why is this and what can I do to fix it?????

Here is a video

 

Thats a stuck/dirty IACV. It would most likely clear it self up once you started driving. Take it off and clean it.

 

throw a can of seafoam or stabil in the gas tank and run for 10 minutes
That will keep the gas from going bad and gunking everything up

Its harder on the engine to be run for 5 minutes than to let it sit unused
The oil needs to get fully warmed and the exhaust, but short cold run only add to the problem

You can shoot deep creep into each cylinder, or do a seafoam `fog to stall`- then it will be ready to go when you are

 

OK I put Stabil in my car. How do I clean the IACV?

 

my cars do that when the vacum hose is pulled off also.. possibly a leak?


but check what the others said first...

 

the iacv is located on the bottem of the TB assembly
remove unit from intake manifold and clean to fix
Dont bother till its ready to run again, quit starting it and getting more crud there!

run engine 10 minutes after stabil added to tank so it gets into things as needed
