I have the same problem on my 2004 LeSabre, I had a dealer reset the code, and replace the gas cap but the 'check gas cap' light came back on. I just live with it. I know that evaporator canister has fuel in it, that may be part of the problem. The car also has 212k miles on it and runs well so I'm good with these minor annoyances.

You need to Replace your Cas Cap. The Seal is bd on it and is allowing air into the Fuel Tank Causing Both Dash Lights. This should solve your Problem.

I have a 2006 Ford Freestar. My engine light is blinking and it wanted to stall for a moment. What could this be? A few months ago I took it in the shop and they said that it needed a tune up. So I had...


No such thing as a Tune-Up

Only Spark Plugs are left from a tune-up,
of 30 years ago

You have a check light on
Now -- they have been on all vehicles
for 30 years.
So I don't see where you shouldn't
know what to do

Check for codes
Diagnose OBD2 System with Malfunction
Repair as needed
