    Here's the week of my 06 TB, 135k: cleaned throttle body (was nasty), no issues after putting everything back together. Tuesday the shift cable bushing decided to fail on the selector side of trans. Repaired no issues, Thursday starter goes out, get out of shop this morning, headed out and no power on acceleration, will rev as high as you want in neutral, but nothing on accel. will go to about 30 mph, then starts to bog down. No lights and no stored codes! $355 so far this week and still can't drive it!! Looking for some knowledge!!

    sounds like your throttle is not opening fully, in neutral you don't need a lot of throttle angle for max RPM. get ahold of a scan tool and read the throttle angle when you step on the pedal. or pull the air filter hose and look inside while someone steps on it,
