Default check engine light
Hi,
Every time lately I get gas my check engine light goes on??? It goes off eventually, but would like to have an idea why this is happening??

I have a 1998 LS400 if this helps.

Thanks!!

I would read the code first. It's an important first step.

try tightening your gas cap first and if that does not work get the code and post it.

get the codes read. even if it goes away, it's still stored in the memory, sometimes under a "pending" code.

What is the exact number of the code? Running lean is too broad.
