I have a 2007 outlook that when driving normal starts to miss at around 40mph but no engine or transmission lights come on. If I accelerate when this happens it goes away or if I accelerate quickly it never does it at all. I had the coils checked and replaced two but no change. I hate to just start guessing at valve body wave plate etc. any help would be appreciated

On my 2009 Outlook, when I had the exact same problem, it was still under extended warranty. Same symptoms. I actually rode with the dealership tech and saw this diagnostic tool readout indicated the cylinder that misfired. So, we duplicated the problem on the road.

This was 4 years ago. Well, Yesterday on my way back from a camping trip, it started doing it again, so, I'll have to find out which cylinder is misfiring again.

I don't know if you went for a drive with the tech, but that's how we found the misfiring cylinder.
