Uneven accelaration

I had the same problem with my 190e. Typically its ussually the fuel pump or the fuel pump relay. I replaced the fuel pump and the relay and it went with no problems.... Ussually the non return valve in the pump dies ...

think simple things first!!!

go through everthing like your spark timing....
your mixture....
your idle speed...
fuel filters....
spark plugs
leads
are all the plugs tight in the head?

manual or auto?

Well if the car revs up to 1500 revs then accelerates it sounds like a transmission problem to me. Its just he obvious thing to look at..... You say "the engine does this its not the transmission". The transmission transmits power from the engine to the wheels....if something like a clutch plate needs replacing then it will rev up like this "then carry on". If its an automatic, then i suggest checking the fluid level, get a full service and check. Services dont really break the bank (well at least not here in new zealand). Another thing it COULD be is the ignition timeing...to far advanced (i think). I cant really tell u alot more as i havent been around the tech speak lately [xx(]

let us know how u get on

just a thought

having a look at my haynes manual, you can check and see it the fuel air mixture is right (thus checking if the engine is being starved of fuel). Take out one spark plug and look at what color deposits are on the electrode. If alls good it should be a brown to light grey / tan colour. If it appears another colour then it could indicate incorrect timing or incorrect mixture
