Chrysler Repair: 99 chrysler LHS, fuel system service, chrysler lhs

Question
My lhs has a engine light that comes on for about two or three seconds then goes off. its been to the dealer five times and it wont spit any codes. The history is empty & resets to zero when car shuts off. When the light is on (on the expressway)the car jerks really hard, then stops when the light goes off. If on the streets driving (when engine light comes on) the rpm gauge raises and the car speeds up a bit. seems like it start during kick down from about 40mph sometimes. Many times at red light, the car will stall out. It starts right back up every time w/out a problem. Its had a tune up, fuel system service, & numerous diagnostic run, Any familiarities with this situation? Suggestions or comments?

Answer
hehe  your dealer or the tech u got must not be vary good at his job. Stuff like that would be either the PCM is loosing power or ground all the time  or the PCM itself is bad. Take it to another dealer or have the one u take it to to give it to an experienced tech.
