Gentlemen,

As stated, took the injectors out and cleaned them, everything back together and i have an idle of 1800 rpm. I disconnected the throttle when i removed the injectors, did the throttle body reset a few times,
no change. 15 minute drive at highway speed, no change. Also no codes. what am i missing?
Thanks

after checking my work, i installed the cruise control cable with one to many turns. Adjusted it back to where it needed to be and idles great.
Thanks.

 

Excellent! An easy fix, can’t beat that! Thank you for the update.
