Hi all,
I'm new to this forum and car maintenance in general but I'm learning fast

. I have owned a 1999 1.8 gti for the last 4 years.
I filled up with petrol on Wednesday drove 500 yards, stopped at the traffic lights and then the car turned into a tractor!
I have read alot on this forum regarding missfires (thanks to everyone who has contributed in the past!) So far I have tried:
Disconecting MAF. No change.
Disconecting each coil in turn to find which cylider is missfiring. Engine runs smoother with the same cylinder disconnected. Identified the cylinder.
Swapped spark plugs around. No joy, same cylinder effected.
Switched the ignition coils (long black things attatched to the spark plug) around. No joy, same cylinder effected.
So here are my questions:
1.From the front of the car looking at the engine do the cylinders run from left to right or right to left? 1234 or 4321?
Working from the air box and MAF (right side) it is the third cylinder along effected. 4
321.
2. Can I switch my coils around to find out if it's my coil pack thats at fault?
If indeed it is my 3rd cylinder missfiring then I will try changing my ignition amp, which just happens to be rattling around the engine bay not attatched to the airbaox.
Next change spark plugs and fuel filter.
Then clean the injectors.
