Check engine light after oil-ch/fuel-inj service

I have a 97 Accord automatic transmission.

I went into Wmart on Saturday for an oil-change. They said the fuel-injection system service was only $20. So I said okay. While driving back, I noticed that the check engine light had come on. What could they possibly have messed up?

Go to an Autozone or Advance Auto, get the codes read, and post them back here. There are a lot of trouble codes, and this is the only way to know if it is related or coincidental.

As busted said, we need the numbers. I will only add that you almost certainly wasted that $20.00. If it is not Baroque don’t fix it.
