did you ever replace the injector? if it is shorted, that was the reason for the computer fialure. by replacing the computer and not the injector too, you run the risk of burning out the new one as well. there is always a reason for computer failures. without repairing the cause, the problem will still be there.

No I have not replaced any thing the mechanic said it was to inconsistant to know what it was after letting it run for a long time no misfire at all at idle. My regular mechanic is the one who said the code 27 and # 5. I am going to try to fix this myself now I cant afford much more than the parts cost. I will buy this from napa. but I was wondering about the procedure? would you use you tube instructions or what would you suggest. Removing pressure from the fuel lines simply means to disconnect neg cable and pressure cap on fuel rail line right? I saw that 15 ft #s were suggested for the replacement of this. Thank you so much for your help. lI am retired on social security and hope to keep this car (94 dodge 5.2) runningl
