ENGINE AND ENGINE COOLING:ENGINE:GASOLINE
AT DIFFERENT TIMES AND SPEEDS, THE CAR WILL SKIP AT TIMES. SOME TIMES IT SURGES VERY BAD AND CHECK ENGINE LIGHT WILL COME ON. OTHER TIMES THE CAR WILL MISS AND THE CHECK ENGINE LIGHT DOES NOT COME ON. TECHNICANS AT DEALERSHIP CAN NOT FIND TROUBLE CODE FROM CHECK ENGINE LIGHT TO SOLVE PROBLEM. YOU MAY DRIVE 300 MILES WITH NO PROBLEM, AND THEN YOU MAY DRIVE 10 MILES AND IT SURGES AND THE CHECK ENGINE LIGHT COMES NUMEROUS TIMES. THE CAR HAS BEEN SERVICED, TUNED AND FILTERS CHANGED AND DOESN'T HELP THE PROBLEM. I AM AFRAID I WILL GET IN HEAVY TRAFFIC AND STALL COMPLETELY, POSSIBLY CAUSING AN ACCIDENT.
