  • Some problems after cleaning TB...

    Went about cleaning the TB today, all went well till i started the car. Car idled at 3000ish so i shut it off and went around looking to see where i screwed up. Ends up i put the TPS sensor in backwards. So after fixing that, i restart the car, it idles normally. I take it out for a spin and i notice the throttle is really sensitive. When i give it about 1/4 throttle, the car starts to idle at 3000 again. Replaced the TB gasket with a new one, so i don't think its a vac. leak. The hose from the IAC to the TB did have a crack at the end where it plugs into the TB, but i used a hose clamp and i think that did the trick for now. If there IS a leak there its small, not one that would case a 3k idle. Anyone got some suggestions about what's wrong?

    Oh and, it threw a code at first:
    DTC P0122 Throttle Position (TP) Sensor Circuit Low Voltage

    I assume that's because it was in incorrectly?
