When accelerating with a load on the engine (full car or up a slight grade) from relatively low rpms (2500-3000), the car will sometimes shudder violently, stop accelerating, and ping.

They said it was running rich, but never stated a reason. I think they just reset it, but the problem never came back, so it was fixed.

This is related to the problem in april...one of two fixes-the first was a valve got stuck with dirt. This didn't work, car lost all power on highway. So did the alternative solution which was to replace an electronic component that controlled the valve. Had to fix the key ignition ... somehow it wouldn't recognize any of my 3 keys ... something happened to the tumblers ... couldn't drive car until locksmith fixed it.
