Any way to adjust the idle on my 09 SM5??
Hi guy's , just asking if their is a way to adjust the idle on my 09 SM5 . It's runs around 1400 and 1450 at idle . Took the side panels off , but still hard to see around front of the throttle body . I did see a screw with blue loctite on it that might do it . But not sure . thanks guys guys

Gilly, don’t touch that. Idle speed on the 998 is not adjustable. You’ll just screw up throttle body operation if you screw with that screw. 1400 - 1450 is only slightly high. If it stays that high at hot idle, and if you’re really worried about it, check for a vacuum leak and run some Seafoam through it in case you have a dribbling injector.
You’ve got some small vacuum lines on the left side of the throttle body. Two for the MAP sensor, and I think you also have one on your version of the fuel pressure regulator. Also inspect the rubber mounting boot of the throttle body for cracks and tightness of the hose clamps. On the right side you have the purge valve line and clutch assist line. I understand that you had some clutch work done recently. Maybe look at that.
