I have a 2003 turbo auto stick, 19,000 miles,airbox silencers removed, use a K & N. Same a started misfiring when engine is under a load (say just before it would change to passing gear). Dealer has changed plugs and one wire number 3 I think?.
When same starts to miss if you use auto stick and go to 3rd no miss, if you travel at 70 or above no miss. if you accelerate through say 55 to 65 no miss does anybody know what could be wrong[:I]
