Since re-booting the computer to get the a/c issues fixed, I've had something else pop up. Not knowing if it's related, but after driving and turning off the car and immediately turning it back on. It runs rough and get a P2176 Throttle actuator control system- idle position not learned. After turning it back off and waiting a few minutes, it starts and runs fine? I've never had this issue, even after installing a Momo ported TB. Anyone else ever have this happen or know a solution? Thanks, L8R ZFLASH
No info about your car? Age of battery? Anything? Knowing nothing I'd suggest you may have a wonky battery; such can cause all sorts of strange quirks, and/or the battery connectors may be significantly corroded. Anyway, knowing nothing more this is somewhere to start diagnosis. All the best.
Sorry, 2016 Z06, 50k miles, changed the battery yesterday to a Diehard AGM thinking the same thing. Took off the throttle controller off thinking it was the problem, nope, still doing it. I was thinking of putting the stock TB back on and trying that, I'm just trying everything that I can do. I'm no mechanic, but I can do a few things before I take it in. Thank you
