Problem started last night when my car left me stranded on the side of the freeway. I was in heavy traffic when my cars idle progressivly got worse and finally died. I continued to try and start the car and it would run for short time lengths at vary low choppy idles. I got up this morning and checked the coil checked fuel pressure at the fuel rail, checked the fuel filter and they all seem to be fine. Fuel pump has been replaced within the last year to year and a half. The car acts like the timing is almost out or soemthing... Any suggestions are appreciated, thanks for your time.
