Rough Idle - 2008 Ford Focus

Cigroller, that’s all they did to it, I wasn’t about to spend a lot of money to have it fixed unless the smaller stuff was done. Really not sure why they didn’t try all the stuff you guys mentioned, but I as insistant on knowing what they were checking just so the next time it won’t be repeated… No, the check engine light has never been on, just rough idle and loss of power. That’s all. What I put up there is all that I’ve had done to it since the initial problem started… Soon as I get home tonight I’ll try the EGR and see what happens… So if I do this it theoretically should just run normal if it is, in fact, the true problem? Really getting frustrated with the mechanics I’ve seen at this point lol
