hi, originally i had the 17704 issue, i installed a new cts and this sorted the problem for half a day. last night it started misfiring. 16684 and 16687 came up, swapped the second and third coil packs, then 16684 and 16686 came up. so i replaced the coil pack and spark plugs. now whenever i boot it it misfires at 3000rpm then loses power. total codes now
im assuming 17704 will be the stat, and 16685 the coil pack, although its not misfiring till i boot it. as for the last one i havnt a clue. i spent my months wages on this thing already and its only been on the road 6 days since i bought it last september. anyone please help, someone i can phone anything to help. i love this car but its really starting to annoy me!
