Hey everyone, I'm new to the Chevy forums but not new to online car forums. I've been into water-cooled vw's for years but have recently purchased a 4X4 Blazer for the winter. All my buddies drive Chevy's and I new it was the right choice! Have a quick question though... The truck starts up and runs strong, but I've been having issues with it bogging/choking when I hold the rev's up a bit more than idle and release the gas? The truck will sometimes bog when coming to a stop as-well. Normal throttle and full throttle truck feels 100%. I have replaced the plugs, plug-wires, throttle body gasket, cleaned all sensors and new fuel filter. Any ideas? Fuel pump issues? Thanks[sm=burnout.gif]

 

Might be that theTPS (Throttle Position Sensor) needs to be cleaned.
