1994 Chevy Blazer K1500

[Rbraczyk]

Hey im new here so take it easy on me. I have a 1994 Full size chevy blazer with 276K. Just changed 02 senor which helped my problem a little. Ok when im goin in reverse, and i let off the gas, it sounds like the motor is ready to stall. Tach drops off, and you can hear the individual pistons firing. Almost like a Top fuel dragster. It also happens when the truck is warm and lets say your pulling through dunkin donuts and your goin real slow and you take a corner and you give it only a little gas. Please help!

Fuel injected TBI. Im changing out the EGR and vacuum lines this weekend. Already changed PCV and 02 Sensor.
