Similar to Philip’s XJS, my '92 has been providing me with reliable
service. Since putting it back on the road about two months ago
(after its winter hibernation), I have put approximately 3,500
miles on it. Other than the electric cooling fans going out on me
(I knew this was going to happen, and just hadn’t replaced them
over the winter), the car has been running perfectly. I put some
Derale cooling fans on and now the thing will idle on hot days with
the AC on and not complain.
But one can never relax entirely with these cars. Yesterday on the
drive home from work the check engine light came on. I am getting a
code Fuel Fail 13, for which I can not find an explanation. Unlike
most FF codes, this one appears to have a running issue associated
with it. Specifically, the car acts somewhat like it thinks the
engine is still cold in terms of when it shuts off fuel to the
injectors whilst coasting. Normally once warm, it shuts off fuel
when I let off the throttle until somewhere around 1000 RPMs. Now
it seems to be 1500 RPM or so, which is what I normally observe
when the engine is cold.
I haven’t checked anything yet, I first wanted to know if anyone
has an idea what this code means!
