I'm doing a Focus service day tomorrow.
I'm picking up some Mercon LV today, so tomorrow the tranny fluid and filter gets changed, the plugs get changed and re-gapped, ECU gets reset, MAF sensor gets cleaned. Will it help? Probably not but it will cost less than $200 before i give up and go to ford. At least the door locks dont seem to stick anymore.
My 1981 DeLorean runs smoother than my wifes focus. I do love the focus though. Very comfortable to drive, great on gas, looks nice inside. I drove (and still have) a 2000 Jeep Wrangler. Getting back into the Jeep feels archaic compared to the Focus.
