this is very weird and I have no idea what could be causing it. it doesn't happen 24/7 but it does occur at least once a day. whenever I am in any gear and I'm accelerating normal and I get off the throttle the RPMs kind of spaz out , fluctuating within 300-400RPMS of whatever RPM it was on when I leave the throttle. the car also kind of jumps back and forth. as if it has some sort of inconsistent gas flow. this only happens for a good 10-15 min and then stops. if anyone can help me out here I'd appreciate it
