Check your fuel pump relay. Its located in the fuse box under the hood.

Hello,

To tighten your engines belt, there is a hefty bolt that goes fore and aft through the tensioner. I think it has a 27mm head on it, then you remove the bolt and you will be able to remove the rod and its double D portion that is what turns the tensioner. This will also allow you to remove the tensioner. The tensioners are a common failure items to inspect it carefully, do not lose the white plastic pointer. It is when you are about to reassemble it back together you will be able to tighten the engine belt.

Take care and good luck

Did the check engine light come on and stay on? There should be codes comming up for this problem.If you have Fire and Fuel the only thing missing is receiving them both at the percise monent. Try replacing the Electronic Ignition Module.Good Luck and have a good XMASS.

Behind a panel at the center front of the cowl near the wiper moter. Hope this helps.

Thank you for using FixYa,com.

Did you try opening the bleeder screw on the caliper it self. If you still can't compress the piston back into the caliper after opening the bleeder screw you may have a caliper that is locking or locked up. Sometimes a big pair of channel locks and a lot of muscle can compress the caliper again. If not you may need to replace the calipers. Make sure to ask for rebuilt verses new. there is a huge price difference.

Fuses first place to start, OVP relay next, fuel pumps then tune up parts

Remove retainers, remove injector and replace seals.

try the kick panel where your left foot rests while driving,close to the door,once the hood is popped ,the lever might be above one of the headlights or its in the grille, if that doesnt work just contact a mercedes dealer

At least a CO90. If the car shakes only on idle that means that the fuel mixture isn't lighted every time by the sparkplug - check the injectors and sparkplugs for dirt.

Does it seem to misfire or backfire?It sounds alot like a trnsmission or clutch starting to go bad,depending on which you have obviously.It definitely sounds like an automatic transmission I would say.If it is transmission,I have never seen good results from rebuilt or used ones.It is best to replace.Call a few shops,they will give a free opinion and estimate usually as it is good for business.Good luck!

sampling motor in the dash that leads to the dome light area may be clogged or ppumpp may have failed. After cleaning and checking that you may have to replace your regulator.

Jack upp one side of car, remove tire, unbolt in truck, unbolt on the bottom and push together and remove.

Buy freon at any auto store at hook up to low side run the engine up to 2K rpms. Low side at 2K rpms should be around 35 psi with compressor engaged. Usually takes 3-4 cans.

You should mean charge the froen, low side port should be on drivers side area near motor coming off the compressor.

Sounds like a driveline type issue. Check carrier bearing and flex discs.
