I took it to...

I took it to a local Firestone on Monday for an oil change, rear break pads replacement, and a fuel injection cleansing. a few hours later, the CEL, VSC Trac and Trac Off lights came on. I took it back to Firestone the next morning and they cleared the lights. Eight hours later, the lights reappeared. I took it back this morning. They recommended that I visit a shop down the street to have my CAT converters checked. I went to my local Toyota dealer who said that 4 of my CAT converters were stopped up because Firestone used the wrong fuel injection. I have a 2003 Toyota 4Runner with 168,000 miles.

Mechanic's Assistant: Does the light stay on, or does it blink?

It stays on.

Mechanic's Assistant: What is the model/year of your Toyota?

2003 Toyota 4Runner SR5

Mechanic's Assistant: Are you fixing your 4Runner yourself? What have you tried so far?

No, the local Firestone did a rear brake pad replacement and fuel injection cleaning on Monday which started the problems. My local Toyota dealer diagnosed the problem as 4 CAT converters stopped up. Firestone claims that their fuel injection fluid is universal. Toyota claims it was the wrong one which has caused the lights.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No, I think I covered it all. Thanks!

Hi I'm David,Firestone hasn't documented any fault codes. The service slip from the Toyota dealer showed P0420 - P0430.

ok, P0420 and p0430 and bank 1 and bank2 catalysts below efficiency, sometimes replacing the rear oxygen sensors on both banks will solve this.
