My 2005 ford focus idols really rough if I am stopped for a short period of time. I have changed my spark plugs, flushed my lines, did an emmissions flush, got my oil changed every 3000 miles and cleaned my O2 sensor. I dont know what else it could be.

Sounds like a vacuum leak. Stop throwing all the odd stuff at it and look at the basics.

The pcv line is common for leaking down at the throttle body.

I would start there before going off on a tangent.

I have no leaks. My dad and I checked that. Could it be the internal computer?
