Probably either a bad cylinder or a bad plug, take it to your trusted toyota mechanic to have a look at it.

Misfire !!!
Misfire can be due to ignition (plugs ,coil ) ,fuel related (clogged injector ,low fuel pressure ), intake leak ,and leaking compression.
Get your car scan and analyzed accurately to nail down the culprit

Exactly what brought me here. My Crankshaft pulley (Engine pulley) got spoilt, after changing it, the car started idling erratically. I ran a scan and it said 0501(Idle Air Control valve Low as expected). I did nozzle cleaning, and plug cleaning. The plug is firing well before now but just decided to clean them.

I changed the air hose leading to the MAF which was broken. Now the car idles at 800rpm and switch off after some time.
The mechanic said two of my plug coils are leaking (he told me before now shaa). So I ordered for 3 coils which is still on the way coming from Aba. Please what do you think about it. For 2 days now I haven't driven the car. The car was fine and moves well before the pulley failure. I am yet to rescan when the coils are changed with my Creader scanner.

Car is 2003 Honda Accord V6.

Thanks. But If the crankshaft sensor is not working, I don't think the engine will even start
