Hello,
I am newbie to the site and I would like to start things off by saying thank you to all who have posted some very detailed info on this site which has helped me out quite a bit with my 94 Pathy XE. While I was driving home last night the engine just died on me and it would not start back up. My Pathy has 186,000 miles on it and was still running fairly well. I have already replaced the plugs, wires, cap and rotor. It has a new fuel and air filter and I replaced all the vacuum hoses. I have also removed the cat and installed a Flowmaster 40 series muffler because since it still had the original equipment and both were clogged. I have cleaned the MAF and installed a ground wire to the frame as well. I am not sure if the pathfinder still has the original timing belt or it has been replaced. Here is the kicker, I was attempting to set my timing and noticed the timing marks on the crank shaft pulley are only visible from underneath the vehicle (this is not good). I set the timing only by ear and checking to see the rpms were around 700. It ran fine for 2 days after the adjustment; the engine seemed to have come back to life. I know this was a no, no, but I needed a quick fix because I needed to get to work.
I had the Pathy towed home and then started trying to diagnose the problem. I checked for any lose wiring, vacuum hoses and clogged filters. I finally messed with the timing as I had marked the previous setting and I fired right up, well sort of. It has an obvious miss but it started. My question here is does anyone here think I am going to have to replace the timing belt? I know the life span on those suckers is around 60 to 105 K and is there any way that cam shaft pulley could have been placed on wrong or has my timing belt lost a few teeth? The only 2 items I have not changed myself are the O2 sensor and that darn timing belt…
Any insight would be greatly appreciated.
