Wish it was an easy fix but a guy brought me a 1994 XRI 3 days ago, that hits a wall at 3200rpm. Has already been to other shops replacing ign. boxs, stator and the manual and electric fuel pump. Found the oil metering rod on wrong, the pulse valve vent was plugged, gasket was not sealing on the pulse to manual pump gasket. Compression is 110-115, all cylinders hitting at low rpm`s, timing is good at 26. I replaced all of the fuel lines, filters, checked fuel tank pickup. Going into the VST to check the needle and seat, clean the fuel regulator next. Posting this to let you know how involved it can get. Fuel lines would be the first thing I would replace.
