Lag acceleration rpm increase but no speed
So I Recently just got a 2009 VW JETTA SE 2.5 engine automatic- and I’ve had
it about a month now - no check engine light has come on but I noticed the
driving gets randomly rough and inconsistent. My morning commute when
entering a freeway on-ramp from a red stop light it takes forever it seems to
regain the speed for entering the on ramp and then merging onto freeway -
also it sounds louder at time of acceleration (and I don’t mean like me revving
up the engine) it will be hesitate if I try to pass a vehicle BUT not every or all
the time .. No check engine lights or any dash lights have come on since I’ve
owned it but I was curious if anyone else has noticed n had a solution to this?
ALSO when starting my car after not driving it for a few hours like say in the
morning after it’s been sitting all night when I start my vehicle it is extremely
extremely loud and shakes/rumbles almost — I wait a few before putting it in
reverse and when I do it JUMPS/POPS in reverse and I don’t even push the
gas pedal my foots no where near it I just lightly and slowly take my foot off the
break … any ideas? I’m always looking for a dash light to tell me if there’s a
problem but from my experience they very rarely come on when something is
wrong lol
