only had the car a few weeks,but it's getting noticably worse.
Starts and runs perfectly from cold,but after about 20 seconds tickover drops to 500rpm and starts missing.
nightmare to drive around town (chugging,coughing,spluttering) but as soon as its on boost it clears and takes off perfectly.As soon as you let off the throttle it misses again.
It's completely standard and has covered 80,000 miles.
I've only tried new spark plugs at the minute as funds are a little stretched and i can't afford to throw parts at it.
Any help much appreciated.
