Anyone know why my manual 04 Acura tl will randomly accelerate itself to 2k rpms and drop to 1.5ish and rise up in 1 second and it does that till I turn it off and turn it back on I had 3.7 smp intake on it but I switched it back incase it was that and change every gasket just incase and no check engine light so I’m not sure what’s going on I also just got it so I need to learn more about it
