Poor Running 240 SX
I have a 93 240 SX with a KA DOHC. Yesterday I was getting on US19 and as I was on the on ramp it started to hesitate in the throttle until about 4K. It almost felt like I lost a cylinder. I have no smoke or water in the oil so I dont thin its the head gaskit. So last night I went out and bought new spark plugs to see if that would fix the problem but to no evail same shit! Anyway I did notice that the back 2 cylinder plugs were white and the frint 2 were black? any thoughts? It runs like its on 3 cylinders but theres plenty of spark? I will shoot some video of my driving the car today after work and post it in here to show you exactly what it is doing. Any thoughts? BTW it has a new fuel filter. I have done a little searching on this hesitation problem but nothing sounds like my exact problem.
