What happened?!

[Francos Yaris]

Can someone help me out? I was driving behind someone doing 10 mph under the speed limit, so when i went to pass him, i stepped on the gas, and the car downshifted like normal, then the check engine light started flashing at me and it cut power to the engine only allowing me to do 40 mph, it kind of went into like a limp-home mode. So i pulled over and popped the hood. The coolant level is normal, the oil level is normal and i have a full tank of gas. I wait 5 minutes and start the car back up and everything is normal again. What just happened?

Connect a code reader (or go someplace that will do so for you). Even If the CEL is not still on, there should a be a stored code that will give a better idea as to what happened.

Yea, i thought about that, but i dont know anyone with a reader. I called the dealer and they said they want 100 dollars to just throw the reader on it...

Many auto parts store will read it for no charge.

Flashing CEL usually means combustion problem. I'm guessing misfire.

Check your sparkplugs.

might need a tuneup

Just got a hold of a scanner. It was a cylinder 2 misfire. I guess its time for new spark plugs. What are some good brands of spark plugs, ill buy them tomorrow and swap em out.
