Defected cylinder

Take to Autozone for a free code read (or the dealer and pay $100). The coil sits on top of your spark plug. Instruction to change your spark plugs are in the owners manual.

No special tools are needed (unlike spark plugs). My dealer wanted 240 in labor to change them (I did all six in 45 minutes).

That time includes changing the spark plugs (dealer wanted another $120 labor for that).

So I in 45 minutes I earned (saved $360) .

They also wanted to charge me $600 for 6 coils until another out state dealer quoted me $350 - then the local dealter matched the price.

I also just learned that dealer give out of state people a 25% discount (I emailed them and got a good price on a part, went to pick it up and the price jumped).

At least the internet saves people thousands of dollars on projects over time if they do a little googling and put forth a little effort in the garage/house.

It's always to google "recalls" with your year,make, model of car from time to time. But it does appear that a mechanic needs to take a look at this before it might become worse. In other occasions it can be a simple fix where the place will just charge you to switch off the light...but I doubt that is the case when this light shows up. Normally that is a sign that something might either be sensing wrong or over heating.

I'd go back to that same tech to take another look at it--on his own time to see if there is anything going on with it. Most of the time the parts are under warranty.

Keep us posted on how things go for you!
