Hopefully you guys are able to help me where no one else seems to. I have a 2011 Honda Pilot, 156k mi which needed the spark plugs changed (cylinder 3 misfire and switched coils to make sure the code was the same). Had a friend change them then the same day and every day since then the car has had a delayed or slow start at least one to three times per day. Sounds the same but takes longer than it is supposed to to turn on. I can't help but feel it is related since it started the same day. I've used every resource and person that I am able to (can't afford dealership) to figure out the issue but no one seems to know. No codes either. Do the spark plugs need to be pulled back out and tightened again, not related or any ideas? At a loss and out of $ and the person who helped isn't anymore because they didn't know. Thanks!
