switched to My son has a 1989 suburban he had put a carb and hei distributor in it.He has a 350 bored .040 and a performance cam.He had 305 heads on it but he had to run race fuel for it to run.he switched back to his old heads and fuel injection.the problem he has now is it is running rich and it does'nt seem like it's hitting on all cylinders.it showed a code 42 but it hasn't came up again.(he had cut the throttle body wires when he put the carb on it.)he soldered all the wires and now it wont start.while hes cranking the engine its spraying fuel,i figure es flooded it.my question is what problems will he have with the computer etc. with this cam? will it cause it to run rich? he also bought a prom sensor from summit and no matter what you do it runs like hell.someone said it could effect the map sensor.I don't know much about them.any help would be appreciated. s/t
