loud high pitch whine on warm startup i noticed when its warm it makes a loud high pitched vacuum leak noise and the engine runs rough. only if you start it while its warm though. give it a little gas and it goes away the higher the rpms get then just stops. any ideas? 96 auto. no secondary air pump but has charcoal canister under hood. __________________ ^being rebuilt^ until then: daily car: 96' Blue DASC'd ti with koni coilovers slowly progressing... weekend car: 85 1/2' 944 Porsche no a/c, p/s, gutted cat, loud as hell exhaust, loud as hell sound system |
