95 3.9 v6 mystery miss fix
hey ya'll figured id let everybody know about a problem i had and what it took to finally fix it. i bought a 95 dakota with a 3.9 v6 2wd. it had a bad miss that literally shook the whole truck and the transmission just flat out doesnt have 2nd gear. bought it and drove it 200 miles the day i got it and have been using it as a everyday driver since. well first thought was tune up (plugs , wires , cap and rotor) and no change. so next i thought it may be a major vacuum leak and did the old spray and check , with no luck. tried a idle air control valve. no change. tried a throttle positioning sensor and it didnt improve. so i started to pull the fuel injector wires off the injectors one at a time to see if it changed. and to my suprise it wasnt firing on the 2 back cylinders numbers 5 and 6. so two junkyard fuel injectors out of a jeep straight 6 and a fuel injector o-ring kit later the truck runs like a top.
