My parents '95 Le Sabre hesitates when accelerating at highway speeds. It accelerates fine from stops, but hesitates and shudders when going up small inclines or passing. Basically, any time you're at highway speeds and accelerate, it hesitates and shudders and just doesn't accelerate as fast as it should. I told him to see if it's throwing any codes. In the meantime, what do you all think. EGR valve? PCM? Something else? It has the 3.8 (of course)
