Stumbling problem with my 95-940. a normally aspirated 2.3. I was on the interstate which went from 3 to 2 lanes and a slow down. The engine ran rough and stopped. I found the fuel pump relay (new style blue in the front row) very hot. I changed the relay and was able to get it started, it ran very rough but by pumping the gas pedal once it got to 2000 rpms it smoothed out. Now I get rough running sometimes. I have changed the plugs, plugs wires, cap and rotor. I changed AMM with one from my 93-940 93 runs fine 95 starts but if I try hard acceleration at about 30MPH it bogs down for a second or two and then takes off. No check engine light.
