First off , i have a 2001 honda civic ex coupe , it starts up like a dime. I let it warm up for a while and a hard rumbling starts and i tried accelerating and it shut off but started again with no problem. Then today It was warm and I take off and I was accelerating and it wouldnt go and the rpms dropped and i had to shut off and start up again!!!! Yes the check engine light is on , but sometimes shuts off. Anyone know what it could be?!?!?
