Maybe you have a bad TB or the idle screw was messed with too much? (I didn't bother touching mine.)
I never did the chip swap on mine (too lazy). Coolant bypass (didn't bother to bleed it) and only have high idle when cold and of course my CEL is always on. (For about 700 miles now) Mine does stick a bit it seems, RPMs hang for a few when slowing quickly to a stop (usually to go over speedbumps). No oscillation, except when I first installed it. That was fun trying to avoid looking like a douchebag revving at every light. (For the 100 miles I had that issue I would just put the car into gear quickly to bring the car's RPMs down to normal and then release.) |

Yup I get the stuck throttle at times as well. Cold idle too, but no CEL yet.

I bought the TB off of m911gt who was selling it because of the same issue. I did the chip swap on it so that rules out a bad chip. Fucking with the idle screw is the only thing I have yet to do because I don't see why that would cause anything other than a too high/too low idle. Plus after I installed it I drove to work and back (50 mile round trip) and it ran flawlessly other than hanging to RPMs a little bit but it sure as hell wasnt oscillating. Also this entire time I have yet to actually get a check engine light You would tend to think with the motor ranging from 1-3/4k rpm it would throw a code. I think my ECU is just being a stuck up whore |

Also Gideon did yours oscillate right off the start? Did it come and go? Or was it just oscillation constant for first 100 miles and then it went away? How hard did you drive it for thos efirst 100?

Possibly you guys running with CELs are in open loop vs closed loop and that's why you aren't getting oscillation

Yeah, it oscillated every time I let the engine go back to idle initially and it was for only 20 miles or so. In that 20 miles I ran it to redline every chance I could. (After the engine was properly warmed up of course)

So I need to start driving like a ricer Also was it really jerky every time you applied/let off the gas? Like on the freeway I hit the gas but it steadily accelerates so I have to let off and every time I take my foot off/put it back on the gass it jerks like a motherfucker.

Yeah it was pretty jerky initially.
It still is really jerky if the engine is cold, but once it warms up it ceases. |

okay so the idle screw was all the way in and I backed it up as far as I could. Let the car idle for about 10 minutes and slowly the idle smoothed out completely While driving I am still getting some jerkyness and moderate oscillation (1-2k) at stop lights but nowhere near as bad as it was. It seems the ECU is actually trying to learn the new throttle body now instead of just being a whore about it. Hopefully it will smoothe itself out some more as I drive it more.
