I have a 1988 Isuzu Trooper for a winter car. Everytime a Make turns the Car Sputter's and Low rpm's when I'm driving straight the car runs fine It only sputter's when making turns and sometimes at low rpms'.I tuned It up changed the fuel filter and check the Timing and Still does It. I can't figure Out what It Is. Any Help? It's a 2.6L 4Cyl
