well reding about cleaning iacv got me all fired up and is making me clean out every thing! i cleand the iacv (very black and thick dirt)that made a big difrence in smother idle. so i desided to look at my throtel body today wow! the dirt is like thik **** man i had used 3 cans of carb cleaner and lots of rubing. well i put it all back to getter replaced ruber vacume line fitings and...... now the truck idles high like 2500 rpms wut the **** i saw a sckrew on the body that adjusts the throtel blade can i adjust my idel like this ?like you do a holley carb? ir is my problem somthing other? I had the idea that may be over the years as the body got dirty some one turned idel up to make up for it, now its all clean and its over kill........pleas help this is my first efi truck im used to 4bbls

disconnect the battery.. the computer has stored data for hundreds of start cycles and it is not yet ready to believe that there is actually more air coming in. hook it back up start it let it warm up and after that it should be good.

option B is you have a vac leak check all the lines near where you worked

about a min is all that is needed, whenyou first start it will go high no matter what but after a warm up you should be golden!. if not vac leak

whats the verdict on the fix? there are few vac lines only what you see. high idle indicates a vac leac not a plugged line
