    Rxp spitting and sputtering

    Over the winter I put on my 05 rxp the following:
    fizzle f1000 I/c, riva air intake, et127 wheel with rebuild, Bosch 48# injectors, riva ecu, supertech valve train, 15/20r prop, fly wheel bolt upgrade, carbon ring, arp stud kit...
    first time I took I out it would idle fine (1700-1800rpm) but when I gave it some throttle it started spitting and sputtering like it was missing. Kinda sounding like I had a blow off valve too. Which I don't. I was told that the ecu and the tps might have to be reset. I check on the candoo pro and it was .6 before I reset it. I haven't tried it yet but anyone think it was the tps being not reset? I had some gas from last year in it that I put stabile in, and I added some new before I tried it too btw. Thoughts anyone?

    I changed them right before I went out. Think I have a bad one?

    Could be a bad one one one with a larger gap and spark is blowing out or maybe air leak?Double check all hoses.

    Ok. Thanks. I thought about bypassing the intercooler to see if there was a leak somewhere in between too.

    If you can pressure test it as is and then youl know if that's your problem.
