I have a 2001 dodge stratus with a 2.4 liter. The motor went out and I replaced it with a 2003 2.4 salvage yard motor. The problem I'm have is I'm only getting firing from the # 1 and 4 cylinders. # 3 & 2 are not firing. Needing answers on where and what I may need to do to solve this problem. I have compression, gas, but no spark from plup wires 2 and 3.
