SOURCE: rough idle and intermittant misfire

I have a 2006 with 37800 miles was told today that the fan motor and radiator must be replaced. When the car started to overheat due to the fan motor not running fast enough it blew the freon out too so now a/c wont work either. The bill is close to 1000.00 Dodge offer to pay for labor as GOOD WILL GESTURE 144.00 to be exact. I have taken it in over and over with the same complaint you have described and was told to get a tune up so I did. Warranty espired exactly 3 weeks ago. My sugestiojn would be to sell the damn thing!

SOURCE: mercedes 350 se w116 model v8 misfires sometimes idles on 6-7 cy

Hi,You need to carefully take out the injectors making sure you don`t break the rubber O rings after depressurising the system,then leave them to soak in petrol overnight,you then need to blow them out with an air blower attached to a compressor,by making a snug fit to the inlet side of the injector,a short blast should make a peeeep noise when you do this ,just a couple of short blasts if you have some carb cleaner spray you can sometimes get the little spray tube in the top of the injector to do the same thing,BE WARNED carb cleaner is very powerful solvent and not nice to you or anything else but is really good at cleaning out injectors so use a rag to catch the spray,I have done this lots of times and is cheaper than new injectors at £120.00 each if they are still no good after cleaning them you will have no choice but to replace them,the fuel distribution heads are also prone for siezeing so you need to check this but if it runs on 6 it should only be the injectors stuck due to dried petrol corrosion inside,Hope it works,let me know
Darren.

ROUGH IDLE 06/E350 MERCEDES - WANT TO TEST COIL PACKS AND CHANGE SPARK PLUGS


If it has not set a check engine light it likely is not a misfire, these models wear out the engine and trans mounts by about 80,000 miles. if it is misfire you will need to read the fault codes and go from there.

Location of idle control valve 89 mercedes 300e


The 'idle control' on the 300e is bolted to the second intake tunnel and is a large zylinder with a 2 pole wire connection on one end and a hose connection on the other end. It is NOT ADJUSTABLE.

Why does my 03 holden rodeo back fires & misfires under load, i have replaced sparkplugs but still slugish?


It sounds like your engine needs a tune up, the timing may be off and the carb may need adjusting to get the fuel mixture correct.

I have a W124 230E has idling problem, and sometimes it goes off


Most likely caused by a dirty throttlebody! Remove the intake hose to the throttlebody and clean around the inside and the butterfly valve as well with some brake clean or similar product! Throttlebodies get gummed up by carbon build up effectively closing off the idle airgap under the butterfly valve!

Car hard starts and rough idles and cuts off when attempting to accelerate this is a1989 230e model, it produces a black smoke


Black smoke is burning oil, blue is unburnt fuel. If you are burning oil sound like valve seals in the head are failing.
