Hi all, I am having trouble with a truck. Its an early 03 that i recently installed warrens stock+ injectors in. Other mods are mbrp exhaust and custom tunes from innovative for the injectors. If you start the truck and let it run it will idle down around ~650. rev it up to 1500 and it will never come back down to the 650 idle, it just stays up there. Same goes for driving, it will never idle down until its completely stopped. It will keep ~900 rpm idle and pull the truck to ~25mph and wont slow down. Give me some help please. Thanks PSN.

my personal truck is a 04 with warrens 155/30 injectors and it doesnt exhibit these symptoms. Ive installed a half a dozen other sets of warrens stock+ injectors to never have this issue either.

I just installed warren 190/75's and it does the same thing but it seems to be getting better with time

mine did that also, but not that bad, and went away after about 100 miles or so
