Hey guys, long time lurker here, I think only second time poster. Love the forums and community here. I just installed the Shark Injector last night. I followed the instructions to a "T" and the install went perfectly. I took the car for a spin and everything was running great, except I noticed the idle was rougher than before the install. The car idled perfectly before (just cleaned the ICV a couple thousand miles ago). Now, it seems like the car wants to idle too low, creating king of a lugging sound. I've also noticed the car "hunting" for the right idle speed after letting off the throttle more than it did before, although not every time. Throttle response is great- the car comes off idle without any hesitation and pulls strong to the new redline. It's only at idle that I'm feeling/hearing the roughness.
I searched around a bit and didn't see anyone complaining about the same thing. I'm thinking it could just be the car "relearning" everything after having the adaptation values cleared by the reflash- maybe it will go away after a few days? Any thoughts?
Car is an 04 6 speed with 82k miles and a K&N intake. I would emphasize that it was running absolutely perfectly before the Shark Injector install and all maintenance is religiously up to date.
Thanks guys.
