Re: ef xr6 running crap
It could be injectors, might be worth getting them cleaned and serviced. I dont know the ignition system on efs, but the modulator or the coil may be on their way out. (Pull the metal brackets off the coil and look for cracks in the insulation) [Modulater ef?????????????? Im not sure.] Or, it could be the idle adjustment too low or something to do with the idle speed motor????? Id probably try the injectors first.
