Hi i keep having my cylinder 2 coil pack popping up all the time.see a post on here that r-tech had a problem with the same thing.decided to take the coil out and check plugs and found that the plug had only been put in hand tight.took it out and its had it.put it back in until i get some more put the coil pack back on and took it for a spin.feels alot quicker and it boosts better now dont feel as if its backing the boost off and no flat spots and coil pack stayed down now result.
what are the best plugs to put in a AUM engine? has any one on here tried the ecs hold downs?
thanks paul
