the car hasn't been run in a long time due to other problems..got it back up after sitting for 4 months or so..now the car seems to idle at around 2000..while driving, the car is fine n when im downshifting coming to a stop it slowly goes down to 800 or 900 or so..then when i put it to neutral..it shoots right back up to 2000...i sprayed the intake manifold with some carb cleaner while car was on n it slowly went down to 1500..took it out for a drive again, and it went back to 2000 at neutral...any help guys?

what does it usually idle at...8-900rpms?

Could be a vac leak, go check ur vac lines. Make sure your EGR valve gasket isnt leaking also

I would also disassemble your IAC and clean it. Then go through the factory setting procedure to lock in your idle.

This is of course assuming you have no other vacuum leaks.
