LURCHING AND VIBRATIONS

1995 GMC Sonoma

Engine Performance problem
1995 GMC Sonoma 4 cyl Two Wheel Drive Manual 154000 miles

I drive a 1995 GMC Sonoma, manual, with 154K miles. The engine was replaced about 3 years ago. Recently while accelerating it seems my truck hesitates, lurches, or vibrates. I can usually correct it by shifting down, giving alot of throttle, and slowly releasing the clutch. I took my truck into a transmission shop and the clutch, pressure plate, throwout bearing, and pilot bearing were replaced. The flywheel was also grinded and resurfaced. However the problem is still occurring. I spoke to the mechanic and he stated he fixed the problem in the cluth, but the engine may also need work (which he neglected to tell to me prior to fixing the clutch). I am just hoping to get an idea of what may be wrong before I take it to another shop.
