Engine Light On!

I fired up my '05 after along winter slumber yesterday and the engine came on and stayed on. Also, the fuel gauge seemed to have a mind of its own, as it would register full (which it is) then for no reason would drop to empty and the computer would register an error message, then all of the sudden register full again and the error message would disappear.

Anybody else who stores their car for an extended period had this happen?

It's a pretty well known fuel sending unit error. It happens to me occasionally during very cold, wet driving. Maybe 6-8 times during the winter. It's annoying when it happens but not annoying enough to take it to a dealer and have them rip into my beautiful car.

If it doesn't happen again or if it happens only once or twice more I wouldn't worry about it.

Have you filled it with fresh gas? gummy gas will cause it to have problems.

I stored my car all winter. It sat in my garage covered with a full tank of gas. Maybe once a month, I'd start it up and run it a while. Finally took it for a real ride on Saturday. Came out of storage just fine. Tires needed some air, but that was all. I have not experienced your symptoms. Sorry.

I filled it up right around Thanksgiving when I put her to bed. Just like permajen, I started her two or three times during the winter, but did not have the fuel gauge problem or engine light problem at those times. Going to have the dealer look at it when I go to get my 18" Bullitts put on.
