I Seafoamed my 02' TL-S yesterday (85,000 miles). I put one can in the tank and followed the instructions by splitting another can between the vac line and crank case.

After my spirited drive and resulting mushroom cloud, my check engine light is on.

Should I just reset it and assume it's a byproduct of seafoaming?

The car runs great, so I don't think I fouled up the plugs.

 

did you check the gas cap to make sure its on 3 clicks. also make sure the vacum hose is reconnected. maybee go get the code read at autozone and se what its complaining about

 

Get the code read and report back to us.

 

Mine did the same, I pulled the clock backup fuse to reset and it went away. I probably blew a chunk of crap by one of the O2 sensors and it needed a reset.

Check the code as NSXNEXT suggested and confirm yours is an O2 sensor issue with using the Seafoam.

 

Reset teh light. If it comes back on get the code read.
