Possibly a bad fuel injector?
How's it going? Im new to this whole nissan thing and I have a 93 240sx convertible.
I'm pretty sure one of the cylinders isn't getting fuel. (the one furthest back) I just purchased my 240 August and I haven't driven my 240 in a few months, so when I started it up the other day it idled a little differently then I remembered...although it may have always been that way... I was already going to change the spark plugs, so I turned it off and when I got to the last plug it was almost completely clean. So the plug arcs when touched to metal, but the engine runs no differently with the plug pulled. With my limited automotive knowledge I'm guessing this is a fuel problem, but what kind of problem?
