When im driving and i shift to the next gear the rpms dont drop, and will stay there for a while. And when its idling, seems like a vacumm leak, but its not, goes up and down. Whats that piece we have to clean out??? I cant remember, i know i've done it before!!!

I believe your talking about the MAF...........Guero.....use alcohol and a q tip and make sure if you have a CAI that you MAF is on the top and not twisted to the left or right.....I had this problem and Don called it "clocking"......I adjusted and cleaned the MAF and it worked.....good luck G....

So its supoposed to be pointing straight up? Hmmm.


And as foir the RPMS not dropping between shifts, I think its supposed to do that.

G.......I just read your thread a little better.....you may be talking about the IAC....or the TPS voltage...... .....I know you have a stick but with my auto and the TFS package I idle a little bit higher and it takes until I come to a slow stop before it drops.............being a auto I don't notice it as much driving because I don't "clutch" it........

ERIC......when I put the last stall in we "tipped" the engine and the blue boots on the CAI "folded" a little and Don suggested the "clocking" of the MAF.....of course I had never heard this but Don has done wonders tuning my car so I followed his direction and loosened the boots and made sure the MAF was at 12 o'clock and it fixed my idle issues.........

I agree that it sounds like a vac leak. That said, there's the dashpot function in the puter programming, but it sounds like your car hasnt done this before Guero.

If you unplug the IAC electrical connector, what happens?

Good luck.

The dashpot function causes the RPM's to hang a little bit between shifts (for smoother shifting). It uses the IAC to accomplish this.

Pull codes and see if you have an IAC or idle control code - these most often wont make your CEL come on.

Then I'd do as everyone else suggested with the IAC.

One other thing: if you have a high idle that wont drop until you restart the car, consider replacing the TPS. Carbon inside breaks up and affects the wiper.

Good luck.
