The Check Engine Light has been on and off several times in the past week. It's currently out (once again).

I used a code reader at the local parts store today.
It reports "Fuel Temperature Sensor 'A' Circuit Malfunction (P0180)".

Ever heard of it?
Got any ideas?
What's the significance of this?

Cheers,
Ed
