Press The Gas Pedal but car doesn't move.
For some reason out of the blue my C220 is a sled.
I press the gas pedal and it goes nowhere. Like it has lost 90% of it's horse power. It moves just really slow.... Take forever to get up to speed.
The funny thing is that it happened as soon as I turned on the AC .... It just has not power, like the motor is not being fed or something...
Any ideas what these symptoms might insinuate?? Maybe Air Mass sensor? Throtle body ? Turbo ??
I am schedule to have the car into the mechanic on Monday but i was hoping i could kinda figure out what was wrong prior to that.
Cheers.

Mercedes is gone physically, but still in my heart.
Correct me if I'm wrong, but don't our cars have SUPERCHARGERS, not turbos? Unless I stand corrected, superchargers don't lag so I don't think that would be your issue.

Sounds to me like mass air or fuel delivery problem. does it rev? or do the revs just slowly accumulate? If it doesnt rev, try pumping the throttle pedal quickly at idle and see if the revs climb faster, this would indicate likely mass air sensor if they do. I would expect to see a check light on by now, although mine took awhile to trigger the light.

as for the lag, when you do a Netural REV, does the engine "MOVE" or is it like a slow REV,
flip open ur hood, and REV it up, do you hear a "SUCKING" noise from the intake? if you do, i doubt its the Air Mass sensors.
and the car only lags with the AC is on?

had similar issue when the accelerator pedal sensor died. after flooring the pedal nothing happened for a couple of seconds and then the car accelerated - like massive turbo lag. I was told the drive-by-wire accelerator pedal has a backup sensor somewhere so its still somewhat drivable. anyway.. problem was solved after having a new pedal installed.

Wanted to update you guys on the car problems.
Th reason the car was not reving/moving was because the inter cooler rad completely blew up, therefore the car could not built any boost. The rad is located on the bottom of the car and there is a good chance that supposebly i might have hit it somewhere which could have caused it to bust.
Anyways the rad was replaced and the car now revs normal again, however my AC now no longer pumps out cold air
Is that rad in anyways connected to the AC ??? Like i mentioned this all went down when i turned the AC on and now that I no have cold air coming from the AC and the rad was replaced is leading me to believe that it might be somewhat connected.
Any ideas ???
