Hi Everyone

wondering if someone could shed some light on a problem I have. The car in question is a 1999 C180 Sport that has developed a misfire when cold, yet when warm and running, it is actually fine unless you give it full throttle. Where at which point it either dies completely or becomes very sluggish and underpowered as if starved of fuel. However if you build the revs slowly it will cruise all day at 80mph and never miss a beat until as I say you increase the throttle and it will lose it power and speed.

I now drive at about half throttle which is great at saving fuel but no good if you wish to pass a vehicle in a hurry. All help and information is very gratefully received.

Hi,
have you sorted this yet? try the MAF maybe?
In the UK there on Ebay for around £35, or it may be a relay ( maybe in the boot) Spark Plugs? ignition coil pack?
I would try the chapest first.

 

Hi Steve

Just fitted a new MAF and it has cured the problem but a big thank you for your response.
