997 Tune Up Needed?

[amenasce]

I have a 2006 C4S with 55k miles. For the past weeks, the car has felt sluggish, with the engine revving to 1.2k when it should be idling (At a red light) and sometimes i can smell what i think is sulfur.

I was wondering if need a tune up or if something has gone wrong?

By the way, what is included in a tune up? Spark plugs? Oil? Air filter?

Cheers,

Andrew

How old is the fuel filter?
Some tuneups get it and some don't.

Or your throttle body and throttle plate may have some build up of crud.

Are you getting a CEL? If it smells of sulfur, your air/fuel ratio may be out of synch. This would not be good for the cats, but should result in a fault code being thrown that you should be able to read. Could be the result of a failing O2 sensor.

No, im not getting a CEL. And the sulfur smell happens now and then, not all the time.
The fuel filter is probably as old as the car (although the car was serviced accordingly and i had the engine replace 20k miles ago due to the faulty cylinder wall issue).
