help!- new PC5 firmware and maps. New coil and wires. 11,000 miles- new idle controler. new cables- all fluids changed- and the shop manual doesnt help. Sporty idles OK but hesitates/sputters at load and deceleration but no 'pops' or codes Ideas? someone else have this? Im about to pull the fuel pump and look at those hoses-I appreciate the help

I'd try the easiest first..........dump 1/2 can of Sea Foam in the tank and take a ride for about 20 miles.
