    Idle surge in Neutral

    On cold and hot starts the idle surges up then down in steady tempo. Almost a 3/4 time waltz tempo. Found myself humming Roll out the Barrel a couple times. Anyhow, it seemed to come on this spring. I’ve had the air box off a couple times checking all the normal things. Nothing seems out of place or noticeably malfunctioning. Anyone (crash) have any ideas outside of a polka party?

    Probably the idle speed controller. Seems to be a rash of them acting up lately. I'm guessing it's a little sticky and missing steps occasionally. Stepper motors can get out of sync with their controller if they fail to respond to commands occasionally. I was able to resurrect mine by getting a little oil inside it.

    I had that replaced by the dealer last fall and everything ran fine until I put it away for the winter and tried to start it again this spring.

    Would an incorrect gap in the plugs cause the erratic idle?

    I don't see why not, particularly if one plug was wrong and the other ones were right. However, I would expect missing at high RPMs if the gap were too large. Too tight? Maybe rough idle. Dunno. I think it's worth a look at least.

    Take a break from rioting and pick up a wrench.
    Anyone seen my 10 mm wrench?

    All my wrenches were used to break windows and glass cases.

    Fixed. MAP sensor hose was disconnected at the air box and SAI was unplugged. Dealer must have forgotten a couple things when I had the stepper motor replaced last year. I reset the adaptive after fixing and all seems well now. TuneECU is my friend.
