    Miss fire

    Hello all. I have a 1996 Tahoe 4x4. Having 'random misfire' codes. Replaced everything in ignition system (from the top down to the crank pos. sensor) except cam positioning sensor. Tahoe runs good when it runs good. When its bad its bad. Any help would be appreciated. Running out of ideas. BTW...
