sounds to me that the PGMI relay is going out.
Changing the relay will only cost you money...I had the same problem on my 1998 Honda accord lx...I changed the relay and that wasn't it...It's the ignition unit that the ignition key turns and starts the car..it cost me $60.00
A continuous thumping noise and floor shaking while driving on a 2000 Honda Accord could mean a loose exhaust system. It could also mean a bent frame or a broken spring.
Ignition switch
My 1998 Accord V6 gets, 25mpg in city driving and 31mpg on the highway at 70mph.
If it varies with driving speed, look for an out-of-round tire. If it vibrates only when braking, you probably have a warped brake rotor.
Remove the muffler
Have your alternator checked
maybe needs gas filter
The car is broken.
wheel bearing?
what causes the light to come on
