Any feedback would be greatly appreciated here! I have a 2001 Tacoma reg cab 4 wheel drive and recently the check engine light came on. It shakes roughly when it idles and has lost power. I assume it is running on three cylinders and have had the spark plugs changed. no help there. Brought to the dealership and they cleaned cylinder 4 connection at coil insulator. This helped for about 3 miles then back to shaking and check engine.... Anyone have any ideas and is anyone else fed up with their Toyota dealership service actions?

What code is stored in your computer - related to the "Check Engine" light?

Not quite sure how do go about getting that code i guess... the dealership didnt even bother doing a diagnostic on it. where do i find it?

Bring it to Autozone if you have one in the vicinity. Dealer or a friendly mechanic would be able to get that for you also.

I have a 95 Taco and had a similar thing happen to me. Took it to Auto Zone, put it on a code reader and found out the cat. converter was going bad. Don't know if this helps but it might give you a starting point.
Good luck!!

Thanks all, seemed to be a bad injector of all things.

That's a cheap fix. Good luck...
