Chevy silverado shaking, slow acceleration

Asked by Jul 22, 2016 at 09:01 PM about the 2007 Chevrolet Silverado 1500 LT1 Ext. Cab LB

Question type: Maintenance & Repair

On my way back from Florida, my truck lost a lot of its
power all of sudden as I accelerated.
Now I replaced the 5th spark plug that says is miss firing.
The shaking drastically reduced but still shakes when
accelerating at the start.
Doesn't shake after the initial start. At times it has slow
acceleration.

I'd do a complete tune up. Not just change one spark plug. Unless you're stuck somewhere, replacing one plug is silly! If your Silverado has over 100,000 miles on it you're due for a tune up. Then go from there if the problem continues. HTH. -Jim
