Re: Help 97 truck popping through the exhaust

If the crank sensor is dirty it will cause an intermitent misfire since the magnetic pickup wont always read correctly same problem with abs sensors on these trucks ring gets dirty mag sensor reads incorrrectly causing ABS problems when hitting brakes hard. The distributors in these trucks really arent distributors anymore They dont have a pick up coil or condensor in them it gets that from the crank sensor (or reluctor ring)but a cap can still cause a problem excpecially if it is cracked, Tune the thing up if its over a 100 grand see what happens clean the crank sensor, if it still happens look into exhaust and then finally valve springs
