[QUOTE="SecondhandSnake, post: 16963205, member: 116684"] I took my one car out for the first time in a shamefully long time. It drove great for most of the map but at hot idle, it was just absolutely rich (0.68 lambda) to the point it would often stall. It had been sitting with E85 in it, fuel stabilizer, and I had thrown some injector/fuel system cleaner in it before driving it. The only thing I can think of that would make it that rich in that one spot is if there's some contaminant preventing the injectors from fully closing. And when you're talking 210lb/hr injectors that are already at their bare minimum duty cycle, it would not take much. Normally I see people with injectors gumming up in the opposite direction- reducing flow at higher flow rates and going lean, but has anyone had this happen at low flows? And if you have, what was the remedy? Did it clear up with some driving and treatment in the tank, switching to gasoline, doing a home clean on the injectors, or did you have to send them out?
