I have a 99 F150 XLT, 4x4, with tow pkg. I pull a 23ft ultralite travel trailer. Two weeks ago I was returning from camping trip when my service engine light began flashing on & off. After a minute or two it stopped flashing but remained on. I immediately checked coolant, oil, transmission fluid, etc. There was no shifting problems, strange noises nor was she running hot. Therefore, I cautiously continued home. Fast forward two weeks.

The service engine light is still on. Now there are white stains on my driveway. Water is comming out of my tail-pipe even at normal operating tempertures. Oil level and color is still fine, same with transmission fluid. Still no knocks, pings or other noises. I know something must be going on, but do not have a clue what it could be. This is why I am here, to ask the experts. What is happening? Who do I trust to take her to without fear of getting ripped off? Thank you.

 

go to checker, auto zone, pep boys etc and get your CEL read, that will probably tell you whats wrong right away, if not post the code in this thread
