OK.....I'll be quick because I need to sleep BUT I wanna get this stuff outta my brain while its still fresh.
1) When I turn off my car it makes a hissing noise from around/under the intake manifold like there is air coming from somewhere...then it stops and thats it. (I took it to a shop and they said that its not cracked? He said that they sprayed around the intake manifold with something and if it was cracked, it would have raised the RPM's some, but nothing happened...so I dont know.)
2) When the car is at idle, I can gently push the gas pedal till the car hits 1000 rpm, and if I let go..it will sometimes drop as low as 500-450.........sometimes about 425..then bounce back up to 600...is THAT normal?
and LASTLY 3) I had found this one by accident...I put my windows down while I was parked..and it'll drop down to around 500 rpm's till I lift off the window buttons..I figure this is semi normal because its sucking power. Is all this normal and I just happen to be worried too much, or is there something legitimately wrong with my car?
