I recently said goodbye to a 2002 Mazda Protege that made it to just over 300,000 miles. So naturally I purchased another Mazda - 2007 Mazda6, 5-speed manual, 91k miles.
Besides the difference in shifting feel being night-and-day, I've noticed that as I'm accelerating and upshifting, the RPMs don't drop immediately when I release the clutch, even when I'm entirely off the gas pedal. There is nearly a full second delay from clutch release until the RPMs begin to drop, leading to a significant pause between gears as I wait for my revs to match my desired gear.
Is this normal, or could my hydraulic system be acting up?
