  • Your Pathfinder Info
    I have a 1988 Pathfinder SE-V6, I bought it in the spring of 2017 and it had 316K miles on it. I have limited knowledge of its past ownership or maintenance history, and what I do know is only word of mouth. The transmission was replaced and had 500 miles on it when I bought it. I have done a little bit of maintenance on it so far, most which is regular scheduled maintenance… -Replaced timing belt -Replaced water pump -Replaced Drive belts -Replaced PCV valve -Had to make a new line/hose for the PCV valve, being that that part was discontinued -Replaced Center case oil seal on the transfer case -Replaced the windshield (had to weld and fill in a rust hole where the wind shield in mounted so that the new one can be installed with a proper seal)

  1. The O2 sensors were good. I asked a buddy who is an auto tech if he had any ideas. He said he thought it sounded like the throttle position sensor was going bad. It seemed easier and cheaper than messing with the distributor so i replaced the TPS. I took it out for a 30 mile ride to test it, i even took it on a mountian road so that it would have a fairly large load on it. I had no problems, so I believe this was the fix...if it comes back i will give an update.
  2. The MAF was good. I'll check the O2 sensors and distributor thanks!
  3. Thank you for your response! Before i took took it on my camping trip, i took out the MAF and sprayed electrical cleaner on the probes and took fine emery clothe to the electrical connector contacts as well. But i didnt try the dieltectric grease. So i ill give that a go an see if it helps.

  5. Hi all, I am new to the forum. I have a 1988 Pathfinder SE-V6 with 316K miles on it and it has an automatic transmission (the trans was replaced 500 miles ago). Recently when I was driving, I experienced a problem with acceleration. I was on the highway going up a hill, and to maintain speed I gave it some gas, when it down shifted to get more power it hit 4100 rpm and started to become sporadic ( rpm fluctuating and engine cutting in and out). This only lasted until I let off the gas pedal a little. I discovered if I didn't press the gas pedal too aggressively it will maintain speed, shift and accelerate fine. On the way home the problem seemed to get worse. It got so bad I couldn't even get past 40MPH, any time the rpms would try to pass 2,000 rpm the engine would start to cut in and out sporadically. I eventually pulled over and turned the pathfinder off for ten minutes. This seemed temporarily fix the problem or reset the vehicle for about 15 minutes. So I kept doing this until I made it the rest of the way home. The next day I took it out for a little while maybe for an hour and it didn't have any problems until the last 10 or 15 minutes. If I put it in neutral the problem isn't present , only when it's in gear. It seems after the car has been sitting a while without running the problem is nonexistent, until it warms up. The longer it runs the worse the problem gets. I have checked the ECU for falts in Mode 3 and received a 55 which from what I read means no faults present. Please help!
