Starts and Idles great! accelerates great. While driving I Taper off the accelerator slowly going slightly down hill the engine seems to cut out or rachet on/off. Will quit racheting as soon as I start accellerating again or let off the accelerator completely. It does this in drive and overdrive. Don't believe that it is transmission related.
The motor is 2-3 years old. (GM create motor) The throttle body itself is very clean.


Replaced the fuel filter, fuel pump and throttle position sensor but it still does this? 3-4 tanks of fuel have been used now after injector cleaner was added and no change.
