I changed my wiring harness today and had my uforce running with no codes and after about 20 minutes it stalled and i had 2 codes flashing on the mil light the first one is P0202 which is (injector circuit 2 malfunction) the second one is P0505 which is (idle speed control error) i tried everything i could think of to resolve these codes i pulled the injector and checked it i removed the dielectric grease from the plugs thinking that it might be causing current to flow across the pins i disconnected the battery every time i unplugged something thinking it would clear the code i pulled the idle air controller and did the same thing i did with the injector and i still have the codes the strange thing is the sxs runs perfect now i let it idle long enough to burn a 1/4 tank of fuel and it didn't stall again and revs normal but i still have the codes any ideas or help would be greatly appreciated
