Yeah Tom is probably right.
The ign coils (ignition transformer) are a very weak link in the 2.0s and I
ONLY buy new ones from the dealer. All of the aftermarket ign coils I have
seen and tested have failed!!! Sometimes after a week and sometimes after a
year but all have failed either providing a weak spark or no spark at all.
;-(

I have heard that using Splitfire plugs can be good if you use the proper
wires to go with it for the added benefit.
I WOULD NEVER USE SPLITFIRES IN MY VWS OR AUDIS. Maybe on my domestic Jeep.
NOT!
I prefer using the stock long life spark plugs!
