Sound like you have either a bad sensor or vacuum leak. To tell exactly, you have to have engine codes scanned. Usually free on many part stores.

Pretty hard to diagnose without a scan tool to check the fuel trims. rough guess is either a vacuum leak or bad coolant temp sensor. But I sure wouldn't replace either of those without seeing the results from the scan tool

Check engine light is on. Running rough. Makes a noise when brake is released.


Check Engine lights ofter notify us that there is an issue with our car. The rough running symptom is indicating the car's computer is causing the engine to operate in "Hobble Mode" so you can get it to the shop for diagnostics and repair.

Check the cap and rotor for internal carbon tracking or, just change them. Also, take a look at the coil when its dark and rainy and see if there is any arcing where the coil wire goes into it.

Check engine light is on, motor runs rough, sometimes stalls


Go to Advance or Auto Zone and have them run an obd scan on it and it will pin point why your light is on and could solve your problem. This is often done for free.

Check engine light on


Did you use the correct plugs? When I mean "correct", did you buy them from a Toyota parts dept? Those engines are designed for a specific plug, and if you have the wrong ones in it, expect problems. many times I have had customer come in with poor driveability, and it turns out to be that they installed aftermarket plugs.
