Wow, this looks like a common problem, seems almost exactly like the same dilemma i'm going through, except the difference is i've got a Mk4 1.6 S.? What happens is i start the car in the morning (when the engines cold), it would start up normally but if i press on the gas pedal and depress, the car would stall.? Also it would stall when i dip the clutch to change gear, which makes it dangerous to go round corners as the car would stall and i would have near enough no control over the solid steering.? But the stalling goes away after the engine is warmed up after about 5 mins driving (without stopping, cos it'll stall).? Took it to AA to have it plugged up and checked, but the computer returned no problems, so they told me to take it to VW to have it properly checked out, but i'm dreading the extortionate prices they'll charge.? Anyone know what exactly is this problem and how much would it cost to get it fixed?
