Check relay.

We use Marine Polish. Use a small drill buffer, polish until clear. Make sure you use polish and not wax.

You are the MAN, Just like you said TRocky, there was a short in the center brake light wiring. Found the short in the rubber boot that connects from the lift gate to the car. Inside that rubber boot the wires were cracked and some were shorting.Repaired the wiring and everything is back to normal.

check whether is there any charging relay in the fuse box.

I am betting on a tire balance. I have had tires out that only vibrate at 60; they were pretty smooth at 75.

Similar to the fiesta it would be under the footwell area on the side panel or behind the small cubbyhole unit . Normally just need a screwdriver to undo the screw and I clip the electric connectors.

many reasons are possible such as needs tune up bad gas idle control needs attention o2 sensors --cat converter - exhaust restriction -fuel delivery are just a few --have vehicle for any codes

Inside the transmission

there are 2 engines 2.0 / 2.3 and they both have chains if you are getting a rattling sound from the cover front the guides are worn or the chain tensioner are worn the guides have nylon chain runners on them and if they wear down the chain is rubbing against the metal arm that the nylon is mounted on if this is a high mileage motor I would suspect this because the chain can not be kept tight because of the worn guides have now caused the chain to be slack and its rubbing against the front engine cover but you must be sure before opening it up that its not the water pump or belt tensioner pulleys making the noise if that's what your hearing the water pump will sound like a marble tumbling around in a can the pulley's will sound like constant friction grinding of the dry bearing inside against the bearing race there also may be a chirping sound of the belt being made from it grabbing each time the bearing catches inside and releases the chain will sound like a constant rattling as if you drag a metal chain on a ceramic tile floor and engine running condition will be rough idling and missing a bit especially when you come to an abrupt stop it may stall

Sounds like a worn gear linkage, If its the 2nd and reverse other than that its the Synchro inside the gearbox, either way sounds like a gearbox off and back on. You can determine the above if you got it looked over by a mechanic thou to be honest theres not much an answer but a rough idea.

Sounds like a vacuum leak, PCV hose or another vacuum hose leaking

I'd definitely check battery and battery cables. In the past, I had a vehicle where the lights at night would brighten and dim a little on their own, drove me crazy, at the moment, I can't remember if battery or battery cables, one or the other. Just my opinion.

Do you know what a wiring diagram is for ? How to use a DVOM - digital volt ohmeter to test electrical circuit's ? None of the headlamps work ? hi or lo beams ? Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. Year , make , model an engine size. Under system click on lighting , then under subsystem click on headlamps . Click the search button then the blue link . Looking at the diagram i see fuse's light switch , multifuction switch , relay's - hi & lo an the headlamp assembly's .

spark plugs good

go to rock auto .com and look up your car and go to exhaust and emissions and you will see pictures of it so you'll be able to find it

Replace the mas air flow sensor. There's a resistor it must have blown already that's why it's not calculating the right amount of air. Also check to confirm if the air cleaner housing is ohk.

It's built into the GEM module (smart junction box) not replaceable as an individual unit.

Check vacuum hoses going to the IMRC for leaks
