Attack of the unibody snatchers! Styling and handling refined or bland? You decide.

Weird Science

Postby lukedion » Sun Feb 27, 2011 7:46 am

2000 Pathy with 140k....Starts and runs fine for approx. 20 minutes until such time that it starts to run rough and finally stall. When I try to start again, rolls over, but doesn't want to start, but sometimes diesels and runs for a very short period of time. Vehicle will then start and run fine for 30 min. when cooled down completely.

I thought for sure it was plugged fuel filter and changed out, but more of the same. Checked all relays, including EGI and fuel pump, swapping out these relays with others that are same. Also cleaned MAF sensor and checked pcv. No codes are up on instrument panel.

I can't for the life of me figure out what the deal is. My thoughts now center on O2 sensor(s), as problems start when vehicle is up to temperature. Any comments or opinions would be VM appreciated.
