2000 Land Cruiser flashing check engine light and the car is running rough/shuddering

Drove fine this morning and then got in the car this morning to come home and it shuddered and rode fought. The check engine light flashed on and off and would sometimes stay off for a minute or two. The shuddering would increase and decrease as well. It happened in both drive and 2nd.

The warning light is telling you the computer has found a problem that is affecting engine performance and fuel mileage. A flashing light means it is something serious.
You should have someone scan the computer for trouble codes and go from there. The codes will help direct the mechanic as to what to test.

Drop in to an Autozone, or Pep Boys, or similar big parts store & they will usually scan for codes free. This will hopefully eliminate all the guess work, or at least point everyone in right direction for better diagnosis. If not obvious from codes what the problem is, get back to us and we'll help you out.

SOURCE: Engine shudders when idling in gear, check engine light on

Take a run into Autozone, or Pep boys, or similar big autoparts store and they will do a free code scan, to point everyone in the right direction instead of guessing, and throwing parts at it. If the fix isn't obvious after codes recorded, get back to us with code(s) and will help you out if still needed.

go to a shop and see if there is a code stored in memory. anything else would just be a blind guess. If you are near an Autozone that do a scan for free

Flashing CEL is an indication of a misfire. You would need a code scanner to find out which cylinder it is.
The code should be a P030n where n= 1 to 8 ( the cylinder number ). Could be a P0300, which is a misfire indication.

Check engine light flashing


Take it by an auto parts store like Auto Zone or O'Reilly Auto Parts and they can connect a reader to your car's computer and give you the codes. Write down the codes exactly as they say, and then find out what that code means for your model car on the internet.

Check engine light is flashing while driving. It seems to be running a little rough. This just happened this morning when I started the car.


The check engine lamp will flash when the computer/emission system sees a problem that could possibly damage the catalytic converter or other components. Often the cause is a cylinder or cylinders that are misfiring which will make the engine run rough. Because the light has been flashing you should have the problem checked out and repaired to avoid any possible damage. Good luck, hope this helps!

First thing you need to do is figure out which cylinders are coming up on the code reader. After determining where on the engine those cylinders are, remove the plastic engine cover and then the air filter assembly. Now, locate which cylinder coil pack needs to be pulled. Disconnect the coil and then remove the bolt holding it in. Pull it out of the cylinder and replace. Perform the same thing for each cylinder which came up as defective. Replace top. Its easy.

Running rough and the check engine light is on?


There could be a lot of reasons for an engine running rough. If your check engine light is on, take it your local autozone they can scan for the trouble codes free of charge. Once you have those codes if you report back here it can help narrow down the possibilities.
Thank you,
