:: On a long trip, I made mention of how well it was running at 80mph
:: Car began sputtering, guages went erratic, and the car shut down
:: Could not get the car started again that day

:: Occasional sputtering when accellerating from a stop
:: Parked car for approx 20 min.
:: When car started, it stumbled & sputtered, but did not shut off.
:: Frequent sputtering, no power upon acceleration from stop
:: when car shifts into second, or around 20mph power returns.
