hi peeps, i gave the cupra a bit of a run today (after not being able to pull away from my brother in his 106 gti to other day). it revs and pulls well in 2nd and 3rd but then missfires at 5k in 4th. its like hitting the limiter and it wont rev past it. 5th also seems slugish but didn't get the...

Having problems with my Leon again. The past five weeks I have had the cam, crank, lambda sensors and temp sender fitted plus new cambelt. Took my car to dealer because it was dropping below 1000rpm when sitting idle and the revs die and the car cuts out. They put it through diagnostics, no...

Car idles lumpy as hell, which is expected from the cams but it wont idle after a rev or if you dip the clutch on the move it just stalls. if you sit on the spot and rev to about 2/2.5 k it starts to miss, but when you drive its fine, other thing is that when you accelerate low down in the...

The problem im having is random missfires on all cylinders but only on tick over runs fine apart from that. ive just changed plugs because i was told it could be that but when iv just run the engine again have noticed small flames coming out of the seats when each cylinder missfires. could it be...

Hi, I have used the search but can't find anything relevent. Basically my car has always felt like it pulls very strong at low rpm but tends to drop off higher up quite a bit. I fitted a boost guage earlier and it goes up to 1.3 bar in third gear by 4k rpm, then it slowly drops down and...
