94 pathfinder-HELP

I posted this yesterday but as I am a newbe I put it in the wrong forum. My 94 pathfinder has 122K and I replaced the MAF and the 02 sensor, plus put in new plugs. It ran good for a week, then developed idleing problems. When it warms up the rpm will go from about 800 rpm to 200 rpm and up to about 1300 rpm's. It then bounces between 200 rpm and 1300 rpm's and then usually dies. Also I think it is dumping fuel in the cranckcase. I changed oil, put in correct amount and when it developed problems I checked oil and it was over full and looked odd. Thanks. jdmangrum

Check the wiring plugs for the MAF sensor, make sure they're tight and not cracked or loose. Check all your vaccuum hoses as well, there may be a leak. These engines are very touchy when it comes to sensors and idling, one dirty part will cause all kinds of problems and it's hard to diagnose at times.

Run your ECU error codes as well to see if it has anything stored.

Thanks, I will check the connections and hoses. jdmangrum
