4.6 nstr. my idle is running to high at cold start-up. It never used to be this way... Any Idea's gang?

 

ses light on? does it idle normal when warm?

 

No ses.

 

check the length of the screw on your igr valve. my screw popped out when i had it up for a year and it was running really hard and fast. i replaced it and now it runs great. your may not have popped out but it could be too far out and pushing the throttle too much... if its popped you'll know too. there'll be some plastic that looks like its at the bottom of the screw dude
