had a timing chain repair & when I FINALLY received the mountaineer back(it took them 2 wk-had to get a special mounting tool & then ANOTHER special mounting tool) the RPMs were out of wack (lower than usual),they did not due an alignment& steering is off(have to drop front axle to remove engine to replace timing chains/belts) I hear a thunk every now & then & when de-accelerating there is a whine to the engine. You can almost hear the engine surging/misfiring. Take it back & they say one of the RPM sensors had come unplugged & the thunk is the sway bar bolt broken. How can a sensor get "unplugged" & can the sway bar get broken when lowering/raising the engine back in after the timing chain repair? drove w/mechanic& he agrees slight misfiring-states old plugs (original)& hears whine when slowing. RPMs dropped AGAIN - sensor fall out AGAIN? they can't look at/repair til monday-state OK to drive til then. I don't have faith in their repair at this point.Can anyone out there reassure me or are they grasping? They charged me $2900 total($300 over their estimate) & charged me for an oil change to boot.when I state had to be done anyway due to oil pan being removed for repair, they state could have added to the labor & not itemized.

I think you need to find a Ford/Mercury specialist rather than whoever you've been using who doesn't have the right tools for a simple job. If you want to find a specialist, here's a directory link for you: https://repairpal.com/directory?address=68104&car_brand_names=Mercury
I was told that my timing belt needs to be replaced. My vehicle does not run at all and I need it my vehicle for work. I would have to have it towed from Cibolo.
sounds like its low on oil when i first start up. rough idle and poor gas milage and has a missfire on three of the six cylinders. have replaced plugs plug wires and coil
