My 91 Acura Integra is only running off of 3 cylinders and is sputtering only in the lower RPMS. What do I do?????? I have been so lost about this, I've changed plugs, wires, distributor cap, rotary button, cleaned out injectors, fuel filter, air filter, I really don't know what else to do. BUT I haven't changed the coil pack yet, which is what i'm about to go do. PLEASE someone give me some pointers!!!!

 

r u getting a check engine light? what happens at high rpm's? hw old is ur oxygen sensor?
