Afternoon all,

I'm hoping someone on here can shed some light! I've got a 1999 1.8t Golf GTI, which seems to have developed a few problems not long after i bought it. Irratic reving -on start up, when slowing down or setting off (Revs range from 600-2200) before often stalling. It also smells like the car is running heavy (MPG can be bad at times) and 'forced' when I try to accelerate. It will also bounce or 'bunny hop' particuarly at 2-3000 rev range but doesn't seem to be much of a problem when driving at higher speeds on the motorway.

Please excuse my complete lack of technical knowldege but I know the mechanic has changed amongst other things:

Temperature sensor, 2 coils, spark plugs, MAF, Cat convertor, throttle cleaned and fuel pressure checked.

He's hooked up the computer software and there are no fault codes detected. The car does seem to run better for about a day after everything has been reset on the computer and then goes **** up again!

Anyway, suggests on what the heck is happening would be great!!!

Cheers
Jon
