Hello just need a little help here, I have a 2010 Mazda 5 with 167k, have not had any problems till now. At 65-75 mph it starts to hesitate but does not stall. Does anyone have an idea what this could be. Just had an oil change approx. 50 miles ago.
I’m also curious if the problem goes away after it happens at speed, or if it persists while you’re continuing to go fast. Had a failing fuel pump in my old Mz3 which did the same... take it above 55 and it would hesitate. Take it above 65 and it would buck and try to stall.
