1999 Explorer Sport
I looked, but couldn't find my exact problem in the past threads/posts. Long story short. Over the last two weeks my engine light (99 Explorer Sport 4.0sohc) came on, pulled codes and ended replacing all 4 o2 sensors (not as hard as I thought it would be). No engine light, I'm happy. Engine light comes back on several days later, code says bad MAF sensor. Replaced that. Car ran fine all weekend, this morning was a completely different story. Ran fine at first then it was surging (like someone flipping a switch off and on, but never shutting down) then my speedo starts jumping all over the place, the radio started cutting in and out and the temp/compass display went all Chinese. Any guesses where I need to start looking?

Bench test the BATTERY first when these trucks have electrical gremlins. Too many have BTDT wasting time on other things. GL
 






Btdt?
