Ok so here's what's been going on the car stated out losing power when going 65or so. It would just act as if it lost 4 cyclinders and then al of the power just comes back. So code said that 3&4were misfiring so new spark plugs and coil packs then I reset the ecu and that seemed to help for a moment. But now the problem is back. Runs fine other than the bogging down and then just comes back. And now it's more repititive?
