I'm having issues on my 88 pathfinder v6. It keeps intermittently blowing the "Fuel Cut" fuse under the dash. After it blows, the truck stays in open loop and idles kind of rough. I've done some googling and it seems the mixture heater grid in the TB could be the culprit. I've tried disconnecting it and also the Oxygen sensor just in case that has anyting to do with and it still blows. I'm not sure what else could be the problem. Anyone have any experience dealing with this? The truck doesn't throw any codes at all after this happens.
The fuse by the way is located under the dash on the top row, 3rd from the right.
Thanks in advance.
