Yo one of my cylinders is missing and I can't figure out why. It's a 1992 240sx hatchback with KA24DE and 5-speed standard. the weird thing is that it only does it during acceleration and idle. It seems to stop missing during deceleration. Already checked my plugs and wires and I'm gettin' plenty of spark. I'm also gettin' plenty of fuel. Anybody got any other suggestions before I tear this b**** apart?

An easy thing to check is the fuel injector. You say you're getting fuel but how can you know if you're getting it during accel? if you have a voltmeter put set it to read ohms, put it across the 2 terminals on the injector once you unplug wires from it. FSM says the resistance should be 11.

There is a lot it could be though, i would try swapping the electronics around the cylinders to see which one is the problem. start with plugs, then work backwards to the distributor. See if it follows anything specific or if it stays with the cylinder. Just make sure you don't forget where things previously went!

well a motor need 3 things to run air,fuel, and a spark and just wondering did you use a fuel presser gauge to see how much fuel presser you have cause just seeing if your getting fuel isnt enough

Swap the injector on the cyl. that isnt firing with another one. If it misfires on the other cyl. that the bad injector went on then you know its the injector. It really sounds like thats the probllem.
