Message Alright guys so I'm having two problems with my Z. It's a 95 NA MT, with a JWT pop charger. The problem(s) I'm having are first, I'm getting really jumpy/sputtery behavior from about 2200-3000 RPM, especially in first and second (and third gear too a little). And the second thing which is possibly related is that not always but frequently when I press down the gas pedal more than a couple centimeters and I'm in about that same RPM range a pump whines very noticeably, and I assume it's the fuel pump. When I bought the car, the guy mentioned putting in an aftermarket pump though ( he said) the original pump still works. Anyone have some thoughts? Also on the pop charger I do have a makeshift flowerpot baffle ( [ http://www.nicoclub.com/archives/300zx-stumble-and-hesitation-fix.html ] ), and I've gone through the FAQ, everything is clean and the radiator just got replaced so all new coolant as well, and the PTU is also brand new.
