2007 Ford Focus runs rough
It got 240,000 automatic and I bought it used. I want your option of this car? It is the first car I ever owned last this long. Also the car runs rough.
Well, if the only problem is that it runs rough, maybe do a tuneup...
-plugs (check the gaps yourself!)
-clean the throttle body, intake etc.
-clean the MAF sensor
If that doesn’t work, check for vacuum leaks. You could also have the computer scanned.
BTW, has the PCV valve been changed?
