Hi, I have a 2012 Honda Accord with about 100,000 miles. For about 2 weeks now, anytime I am on the freeway or the RPMs are above 2000 there has been pretty heavy vibration in the gas peddle and the engine is very loud and sounds like a go-kart. Any ideas? Ultimately the car has no problems driving but it feels like it is just around the corner from a major issue. Any ideas of what it could be would be much appreciated. Thank you!
