Please Help, I Am In Need Of Assitance, I Purchase About 30.00 Worth Of Bad Gas And I Have Already Spent About 600.00 And Still Have Problems... When I Started My Engine Would Just Spit And Sputter, I Installed A New Egr Valve, Tps,o2 Sensor, Plugs, Plugwires, Distribitor Cap And Rotor Button... None Of This Helped, Removed And Installed A Fuel Pump Regulator... Now My Engine Runs But.. Before On Cold Start It Had A Fast Idle Until The Engine Was Warm... Now It Doesn't Do This.. So I Installed A New Map Sensor And A New Idle Speed Control Module.. I Also Inspected And Replace All Vaccum Hoses And Checked For Other Leaks... Why Doesnt My Engine Run Like It Use To..it Also Has A Hesitation And Kind Of Skip To It @ About 55 Mph When The Trottle Is Released It Doesnt Down Shift Immediately But When It Does Its A Little Rough Please Help Me If You Can....!!!
