read the diagnostic OBD-II report...that will tell us where to begin~

you can ask at NAPA or advance auto parts or anyone to come out to the car and hook-up a diagnostic tool that will tell us where the trouble is~ or just buy one for ye self~

THESE ENGINES ARE MACHINES, MUST BE KEPT UP @ ALL TIMES, CLEAN OIL, AIR AND FUEL FILTERS NEW, 6 MONTHS TO 1 YEAR MAX.... BRAKE FLUID CHANGED EVERY 6 MONTHS, NO STORING THESE CARS FOR LONG PERIODS OF TIME, DRIVE THEM, ITS THE BEST THING FOR THEM. OXYGEN SENSOR NEEDS CHANGED YEARLY. THIS BAD GAS WE BUY WITH ETHENAL IS KILLING OUR ENGINES, SCREWING OUR SENSORS, ETC., CHECK OUT SOME ADDITIVES FOR THE GAS AND OIL TO HELP FIGHT THE BULLCRAP BEING SHOVED DOWN OUR THROATS. YOU WONDER WHY WE ALL GOT CAR PROBLEMS ??? TAKE A GUESS. BACK IN THE DAY, WE NEVER HAD THESE PROBLEMS. NOW ITS ALL WE HAVE. GOOD LUCK !! HOPE YOUR UP AND RUNNING SOON.
