Idle above 1,000 rpms??

[StangGT96]

Yestesday at night I raced a 93 mustang Cobra. I noticed after the race that my idle if above the 1,000 rpms (around 1100 rpms to be exact) then drop after maybe 15 seconds to 750 rpms. Also I noticed that every time I turn of the car it makes a wierd suction (sp?) noice that it never made before. I looked at all vacuum hoses and they seemed fine. Any ideas?

P.S. I won both races by a car length. He had cold air intake and full exhaust (LT headers, H-pipes and flows)

my car idles just over 1000 for a few seconds once i stop then goes down to 750... i always thought it was so that it kept enough pressure on the hydraboost system as well as emmisions.

use carb or brake cleaner in a can spray everywhere but the air filter and listen for the idle to go higher mine did the sane thing and it was a vacuum leak

Yeah you have a vacuum leak somewhere past the MAF.

PS: dont let killgore see that race talk

you should consider cleaning your IAC out
