Hi all,
Have just bought myself a 1999 CLK 320 as a replacement for my 1995 C250 but every now and then it seems to lose power.
If i stop the car, the engine is idling roughly. As soon as i switch the engine off and then back to on it clears. She hasn't been run much in the last year, only thing I can think of is a plug breaking down, fuel filter blocked or even a plug pack breaking down. The baffling thing is why does it clear if the engine is turned off then back on ?

Has anyone out there seen or heard of this before?
Any advice or tips would be gratefully recieved
Many thanks

I had somewhat of a similar problem. you need to replace the wires and plugs my friend. while your down there change the engine and transmission mounts to. then your good to go.

 

If it resets itself after a key start its not the mounts.

My money is on the MAF sensor, they go down for fun....its a five min job to put it on the STAR machine at a dealers or indi (i pay £55 for the indi to read and clear any fault codes that are giving me a problem...thats if they will clear due to being a glitch rather than a problem)

Dont get a cheap MAF from ebay, there crap, get a propper bosch unit, you can fit it your self in five mins, under the bonnet on the left theres a black pipe running from front to back about 3" diameter, you will see a black......erm...thing about 4" long with a milti plug in it, unplug it and go for a quick spin, if things are back to normal its the MAF, you will see how easy it is to change. do a google & ebay search to figure out which part it is.
