1997 dodge ram 2500 4 x 4. This thing is driving me crazy! I have replaced everything I can think of and nothing solves the miss. Ive replaced 2 oxygen sensors, plugs, wires, cap and rotor. Diagnostic code said oxygen sensor again so I replaced it again, still reads oxygen sensor! Replaced the map sensor and it helped for 5 miles and right back to the missing again. Maybe I got a bad distributor cap? No codes are coming up yet but the miss is horrible. Runs fine when cold until you get to 45 mph then its all over, misses in all ranges, and stalls out when you come to a stop. Please help cause I you can see this is costing a small fortune!
