I have a c280 sport on a 96 p plate and 114k on the clock. It has been regularly serviced but when up to temperature I am getting an occasional 'spitting' almost like a bag of hammers from the engine when accelerating away form hazards. This does not happen when cold and is intermittent. I eventually took it to our nearby merc specialist who put it on a diagnostic test and it spit out the codes for a faulty Air Mass Meter (At £180 a throw) I tried a proven one of a friends vehicle and the problem is still the same. I am told it could be the oxygen sensor - would this give out the same fault code? and would I get an engine warning light on if this failed?
Any help appreciated. Thanks!
