Ok soo I went on vacation for almost a month, I come back an go to take the 2 out on a nice day and at first I start it up an 2 sec later it dies... so I check the afm connection an clean connectors up a little to make sure. Try starting again an 2 sec later it dies.. after trying a few more times an tinkering around a little bit it stays running but at first it idles rough then it lvls out after a few min. However as soon as I WOT i loose all rpms an almost dies then let off an rpms lvl back
