Bad miss or hesitation in overdrive
Posted 18 March 2006 - 10:38 AM
I can also make it happen at lower speeds. As long as the truck is in OD I can give it some gas and at a certain point the miss or surge develops until the truck downshifts or I let off.
Has anyone else experienced this?

I had the same problem with my 2000 4.8 Silverado. Changed the plugs and wires and all is well again.

The funny thing is, it only seemed to happen in Overdrive and when I load the throttle at low RPM.
I'm starting to suspect a fuel issue. I noticed tonight that when I rev the motor it stumbles off idle if I give it a little too much gas.
I dumped a can of Valvoline Synpower injector cleaner in tonight. I have about 400 miles of highway driving to do tomorrow, so it should get to do it's job.
