I need some wisdom. New to the forum - There's some good info on here, thanks. Here is what I have. 03 RKC, 28k, Hooker exhaust, Stage 1. Ran great last Sat night, Sunday, it idled high at start, rolling, it started sputtering at 2500rpm. I thought maybe bad gas. Changed that out. No codes, no engine light. Dealer said start with the TPS. Changed that out today. Now it idles higher (12-1400). On the road, it sputters, almost dies at 1500-2000, I have to crank the throttle and it blows through it. some backfiring also. same at 3k. It also almost dies as if no fuel then POW, it takes off again. I did the wiggle test too, no change. I think I have too much info from reading on here. Before I let the dealer take all my money, whats my next step? Fuel Injectors? AIU? ECM? Battery? ( see what I mean about reading too much?). i'm thinking injectors. Any help will be greatly apprecieated. or should i just punt and take it in?
