I have an intermittent hissing noise on drivers side when accelerating only at low speeds and also an intermittent judder. The car is a 2005 plate with 40,000 on the clock and has just been in for a new compressor on the air con. Also its a bit of a sluggish starter especially first thing in the morning. To me it sometimes sounds like its misfiring but i,m no expert on these things. Any help would be greatly welcomed.
