Coil went bad.Check engine light came on - why so expensive to replace 1 coil??? on 2006 Toyota Avalon

My "Maintenace Req'd" light came on in March. I continued to drive car @ 1000 miles (2 months) as there was no noticeable problem. Engine ran fine. Then on May 31, the check engine light, VSC lights came on, and I noticed car running rough and losing power, so I took it to the dealearship the same day. They pull codes tell me 1 coil is bad; cylinder not firing, and causing unspent fuel in all 6 cylinders. Cost to replace the 1 coil, fuel injector clean, O2 sensor clean, emission and catalytic converter clean and replace all 6 plugs -- cost is $1600! Car only has 53,000 miles; oil changed regularly, etc. This is my only problem -- but, wow! I though Toyota's were built to last! Dealer say it is rare for coil to fail -- but looking on this and other forums it appears they go out frequently. I considered replacing all coils -- adding another $600 to bill. Will wait for now. I know dealers are always high priced, but this seems crazy. Any one else have experience with coil outage and what did it cost you? Thanks.

Which coil? Some are harder to get to than others, more labor required. That does sound a bit high though, I think. However i dont work at a dealership either! Parts i figure about 250.00 tops!!

Thank you for the info. Not sure... but they said it was one that was difficult to get to...lots of things had to be removed -- Naturally! It was also the cleaning of the fuel injectors, replacing all spark plugs, plus cleaning the O2 sensor, cat convertor and all related systems that were messed up do to the 2 months of driving with un-ignited fuel running through everything. Or that's what I was led to believe. I probably should have taken it to the local Toyota Dr a shop I've always had work done. But thought the dealership could get to it more quickly. They did, but there is a huge price to pay! Never again!

I would recommend using the RepairPal estimator. It is very well set up and being a RepairPal shop we sign an agreement saying we will abide the RepairPal quote. This is a good way to be sure you are paying a fare price.

I would recommend just replacing the coil pack only. If the check engine light comes on then replace the cat. But I don't think you need to do everything all at once.
