I just changed the injector pump on my 93 with the E40D and my light blinks so I called up the tranny shop that rebuilt mine and they say that you have to have a computer adjust the TPS so now I gotta tow my truck in 100 to the shop so they can adjust it *sighs* anyway just thought I'd tell ya why mine blinks. I guess the TPS messes up the computer, they tell me it will ruin the tranny to drive it like that and to have it towed in
