Well I would do plugs, wires, cap and rotor and coil, and also a new fuel filter. I had # 5 always throwing codes I did all that and she runs like a dream. Now I did a new distributor cause I broke the tabs off the old one. But your lookin at around 200-250 dep. On the brand but stay with ac delco plugs. I have 174000 on my 98 and she runs beautiful. I doubt its an injector. But try some seafoam or chevron fuel cleaner. Good luck. Any other? Just ask
