Sticky Throttle Problem

[nhopman]

I have to hose the butterfly linkage with WD-40 a couple time a year to fix a sticky throttle at idle. I'd try that first.

If that doesn't help then

Take the throttle body off and try cleaning the inside of the throttle body and linkage with throttle body cleaner or I think I just used brake cleaner.

You don't want to get either of those on the MAF sensor, there is a spray specifically used for the MAF sensor.

Then give just the linkage a shot of WD or other lube and see what that does.
