Is motor Blown

unless you hear a noise that sounds like a loud clanging when you run the car odds are that your motor is not blown. what you describe could be caused by several things, blown head gasket, motor doesnt always overheat with thse. could also have a valve broke or sticking. also a very likely cause is a clogged catalytic converter. i would check there first. all you need to do is un bol the exhaust before the converter and see if engine revs then. it will be loud but if it revs youve found your problem. and last but not least these hondas have something called limp or safe mode that happens when the car ecu detects a critical problem most often in the tranny and it will cause the car to barely go. but should not smoke. hope this helps u
