i unplugged my O2 sensor and nothing happened no c.e.l., no code and did nothing to the idle. also when i unplugged the iacv not much happened but i did get a c.e.l. and a code 14. finally i tried testing my coil wire that goes to the distributor and i cant get a reading on that. which if not all of these could make my car hesitate and back fire on accelerating especially when at normal temp.

 

Out of everything you stated the Dizzy would be the one to cause it. The missing o2 sensor would just make you run more rich, and they actually have a IACV delete.

 

ok issue solved it was a bad spark wire coming off the msd blaster 2 coil going to the disrtutor. i think maybe replacing the cap and rotor really gave it the juice to really fry it. after cleaning the iacv and replacing the gasket, replacing valve cover gasket and grommets, spraying carb cleaner for vac leaks, bleeding the coolant, replacing underhood fuse box (which did get rid of the code 20), replacing plugs, testing the spark wires (i guess i forgot to check the coil wire which was bad), adjusting the idle screw, replacing the oil pressure sensor and checking countless other sensors, it was a damn spark wire. thanks for all the help.
