I replaced plugs, wires, dis cap, and the rotor and now my 92 dx runs horribly. It starts quickly but it shakes, sometimes quite a bit, sometimes less, depending on the RPM. I pulled the wires while the car is running and it seems like both cylinder 3 and 4 are misfiring. However, when I pull the wires for those specific cylinders, then make a popping noise which makes me think they're grounding(the wires work). So I switched plug 1 with plug 4 but the samething happened. Maybe there's no enough juice to jump the gap. Everything is snug and where it's supposed to be, checked it over several times...thanks in advance

 

oh man, I'm a dumbass, nevermind, the timing was off.....the pro runs great!

 

good to hear you got your problems fixed.

 

thanks man. But the goal of the tuneup was to improve idling which it did...it now remains steady at about 700 rpm, but if I tap the gas, the idle drops below 600 and then goes too high and basically oscillates for a while till it comes back to about 700. I had this same problem before.

 

that is what mine is doing. it could be a small leak in the intake hose. or another vac. leak. what kinda of shape are your hoses in?
