Hey Everyone,

This is my first post...

My 2000 XLT has had a bit of a problem for awhile.

I have been noticing a bit of a rough idle especially when cold. My CEL came on for a P1131, if I remember correctly.

I was told by the person who checked it out for me that it could be an old o2 sensor, a leaking intake manifold gasket, or a vacuum leak.

So now I have replaced the sensor and drove 500 miles before it came back on.

I have not had the CEL checked out yet but I plan on doing that soon.

Thanks
