Hi was going to change my spark plugs because when i hits 80mph it jerks I think i's because I had it superchiped like its losing power was recomeded to change the plugs or coil pack will do plugs first but one thing how do you get to them does anyone know looks like you strip half the engine could anyone give me some advice many thanx

 

on the drivers side you take the air box off, and on the nearside you take off the battery and washer bottle and just take your time and make sure you dont cross the thread on refitting them you could just take them out to regap and inspect them but by the time you have done that you may aswell stick a set in,
as for the coil packs while you have them off check under the boots around the base around the base of the coil pack for cracks or any other obvious damage.
