    rough idle

    Hey guys,
    was just hoping someone can help me out here i have just instilled an up pipe to my
    "99" wrx and now when warm the engine will not idle it revs from 1k to just about stall continually.
    not sure if it as a sensor problem or if it is as simple as a split pipe somewhere i have had a good look around can't see any problems any help much would be great cheers.

    Do you have any other mods or is the uppipe it? Did you use new gaskets and torque everything to spec?

    i have full 3ince system from turbo back, high flow air filter in standed box,i am running 14psi,98 ron fuel.
    i used the old metal gaskets as they were still in good nick.
    no i did not touque them to tollance.
    could this be because the ecu was reset???
    could it be the exhaust sensor now reading different???
    i did'nt have this problem before instslling the uppipe.
