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.

These cars are very sensitive to bad gas caps. Either they are in bad shape or not on tight enough.

If the light is still on or running rough, check the cap, clean it or replace it, tighten it.

To clear the light, remove the battery for a bit

Runs smooth then runs rough & rough back to smooth running.


If your check engine light comes on get it checked. To me it sounds like an engine misfire probably cause by a coil pack or spark plug wire going bad. The misfire should cause the check engine light to come on maybe even flash if the misfire is bad enough

You have to find the reason the check engine light is on. This will aid in diagnostics. Also, are you buying fuel at the same place both times?

With that many miles, I would expect to find the injector as the issue. But it could also be a sticking valve. Or a valve that has problems opening as the oil gets hot. You may want to do a compression test hot and cold too.

Check engine light comes on temporarily - engine chuggs at idle


Before changing you pcm try cleaning your egr valve. remove the valve and see if its stuck in the open position if so use a small pick to clean around the spring.
