Hey fitted mine last week and not 100% sure i put the little vacuum gauge thing back onto the right connection, there are two plugs the same that the vacuum thingo can plug into , one has pink wires and the other has different colored wires , been running it all week with it connected to the pink wire plug but im not sure it's running correctly , seems to run rough at times and starting to get backfires on the odd occasion when i throttle off from around 3000rpm and change down a gear . Fuel economy is still fine , induction noise changes at around 3000rpm sounds like it's slightly off timing by the sound coming from the filter, is that normal ? Im assuming the vacuum thing is like a vacuum advance or something ? Can someone please give me a heads up on what plug it goes back into so i can eliminate it from the cause of the misfire.
Even at idle the tacho jumps a little bit and a intermittent miss can be heard occasionally , would the spark plugs need changing after only 16000 klms ?
here's some pics of the vacuum thing and the plugs
