My 1998 Toyota Avalon check engine light is on! Help!

(1998 Toyota Avalon)
I heard about the Seafoam Treatment. Just tried it today. Also heard it could be O2 sensors. Taking it to Auto Zone to test it. Could it be anything else?

Better off having professional scan test - parts stores can’t even come close!

They can only read codes - that’s a far cry from a real scan test.

Do not waste money and time replacing parts based solely on trouble codes nor the recommendations of a PARTS SALESPERSON - they love to sell PARTS !

Good luck!

In defense of SeaFoam products - it is a good preventative maintenance fuel stabilizer that is used primarily in the small engine / boating industry..

“Preventive” - - it is not designed to be a cure for an existing problem and must be used as directed - as with most products!

Yes, every product has a use. Unfortunately, many products that have value are often marketed for purposes that they are not useful for, and in some cases can cause more troubles.

Exactly!

There is no such thing as magic in a can - related to automobile ‘repair’..

Seafoam... oh boy. I recently had a client who used this that caused all kinds of problems with their vehicle as a result. The moral of the story is: there's no magic solution to vehicle problems, and no mystery oil that is a fix-all.
