GMC Repair: GMC Yukon Shuddering During Acceleration, gmc yukon, miss fire


Question
Hi Pete,
I own a 1995 GMC Yukon GT, 112,000 miles with a 5.7L TBI.
The problem I am having a hrd time recitifying is that at any speed while accelerating, there is a shudder felt throughout the vehicle. As soon as I let off the gas, the symptom goes away. It does not shudder at idle.
I have checked all vacuum hoses, confirmed spark at all plugs, and have replaced the fuel filter.
There has not been any recent work completed on this SUV and the problem did start suddenly. Just a note, this vehicle is mainly used for trailering and the shudder does decrease when I am trailering.
Any assistance you can provided would be appreciated.
Thank-you,
-Bill
