I recently came across a 1993 300zx TT with 90k miles on it. It has been sitting about 3-4 months, and it has alittle "hiccup" when idling and alittle bit of shuttering up to about 2500 rpm. I was wondering what this could possibly be.

The P.O. bought new coil packs right before I went to look at it. What I was thinking it could be is, fuel Injectors, Spark plugs/wires, or a vacuum line... I dunno. It doesn't seem like it lacks power or anything.

I have him talked down to $5000 for it. What do ya'll think, is it a chance worth taking? I honestly don't think it's a major thing. Could be just old gas. any input would be greatly appreciated.
