Engine Sputter-No power
 

I just bought a 98 C230. After I did a tune up, (new oil, plugs, air filter), I have no accelerating power. Whenever I accelerate fast, the engine loses power and begins to sputter. When it does that, i turn the car off, then restart it, and the sputtering is no longer there. Also, whenever I start the car and turn the A/C on before I put the car in gear, the engine sputters and shakes. When i turn the A/C off, the problem goes away, until i accelerate fast/normal. I have to accelerate slowly in order for the engine to not sputter. What could the problem be? I want to know if its an easy fix or do i have to take it to the dealer?

Hi cgmitch, do not take this as gospel, however I had a similar problem, I changed plugs, filter and was about to change the coils when I read a post on another site that mentioned the Mass air Flow unit. I removed this and cleaned it with what I thought was carb cleaner, did not have my glasses on and it was something else. tried the car and it was rough as hell, so purchased a new one and the car ran fine. not sure if the a/c has anything to do with it. hope get it fixed soon, if you are in the UK eurocarparts they may not list it you have to phone

Sorry people did not realise this was dated 2011, will have to use my glasses more often, seems to cause me some problems
