My mechanic cannot figure our what is wrong with my 2002 GMC Yukon. For the past 2 days, acouple of times a day; When acclerating, vehicle drives normal, shifts normal but all of the sudden car jumps (bucks). To give u an idea like when cruise is set and u are going up a hill and your car jumps because cruise is trying to keep up with speed. Thats the feeling. Do u know what it may be?
