Did he say you were gettig a lean codition, was it a lean code? If that is the case it sounds like a vacuum leak with the intake. Or it could simply be a tune up. Try to spray water on the plug wire and see if it miss fires. If that is ok check the distrubitor cap for corrison and the same with the rotor. Let me know what happends.

99 percent of the time a jerking or bucking going up a hill is cured by performing a complete tune up, cap rotor and wires and spark plugs. Let us know how you make out.

It probably was not filled properly when the oil change was done. Monitor it again in two weeks and get back to us

Just under the operation range line. Their is no leaks that I see I park in the same spot at work and their is no oil on the ground. It runs great! Also I had a wreck in it, I hit a deer, I already replace the parts for it. I think I might have to go to higher mileage oil, it have 215, 00 mile on it. Im using valvoline 10-30
