Hi guys, my name is Joe. I have a 96 Pathfinder and it was giving me problems, squeaky belt, loss of power, thought it was the alternator, ended up being the harmonic balancer broke in half which seems to be a common problem. Anyways I got the part and replaced it. Put everything back together and now it won't stay running. Exhaust smells really gassy as if its not sparking. The harmonic balancer seems to be working great now though. If I rev it up it will stay running but as soon as I let off it wants to sputter and stall. I know putting on the HB that I turned the crank. Is it possible its the crank sensor causing it not to fire right? MAF sensor? I checked over everything I did twice and all the hoses seem fine. It was not running rich like that when I pulled it into the garage to work on the balancer. Please help?!?!!?!
