You may have a bad coil pack - try moving two of them around and see if the misfire follows the coil pack or stays at the same cylinder. If it follows the coil pack, get a new one. If it stays in the same cylinder, inspect your spark plug wires and make sure the plug is gapped correctly.

SOURCE: check engine light air Fuel mixture

When it comes on again let a regular shop scan it for you with a good scanner so they can see whats going on. a generic code reader wont do it. if it is stored in memory they can still check it. if the truck runs good idles fine just watch out for anything out of the norm , what about air filter and fuel filter have they been changed ? tune up ? air filters should be changed every 2 to 3 oil changes and fuel filter every 30k depending on fuel quality there. and tune up at 60 to 70 k even though they probaly said 100k.

Honda accord ex 2001 check engine light suddenly came on, car started to idle roughly


If it's running rough, chances are that it's misfiring. If the Check Engine light is flashing/blinking, it is definitely misfiring.
If that's the case, drive it as little as possible... Or straight to the mechanic because the more you drive it while it's misfiring, the higher the chance is of you ruining your catalytic converter.

Sounds like an internal problem. To be sure you will have to drop the transmission pan and check the color o fthe fluid. It should be pink. If it is white then you are going to have to get the transmission rebuilt.

The pressure control solenoid needs to be replaced. It"s under the side cover on the transmission on drivers side. Not a simple fix at home. You will also need a side cover gasket. The transmission does not need to be rebuilt.

Check your cooling system for antifreeze. Also check for any leeks from the radiator, hoses and water pump. If they all check out to be alright check or replace the water tempreture sensor. Hope this helps to solve the problem.
