what's up guys i have a 95 impala ss and i'm having trouble with my idle. I have already replace my IAC and TPS sensor and cleaned my throttle body. I'll triple check for vacuum leaks but none that i'm aware of at this time. It seems to only happen after i go WOT and when i seem to come and park the car i notice that it is idling alot higher than when i first started. Any suggestions, as of why it would it would do this and what I could check thanks.
