 91 mustang prob 2.6 lt
My prob is that my car runs great then out of no where wants to die. feels like it is starving for fuel but has new fuel system. when i get to about 2,000 rpms on the freeway it starts to kick and spudder then will start going again once i get over 2,000 rpms. sometime at stop signs it will die when i hit the gas then sometime it acks like it is going to die then picks back up. then sometime it does nothing. i thought it was mass air flow sensor but it check out fine. what do you think it is??? |
