If it's a spark problem, you won't notice much difference when you hit the bad cylinder. If all 4 make it worse, then try fuel. Pull the connector from one injector at a time - same thing, if you pull one and little change, that's the bad one. If that doesn't ID a bad cylinder, then the problem is probably systemic - bad timing, coil, cap, rotor, computer, fuel pressure, sensor, etc. |
