You had to have it towed?
How embarrassing.

That’s part of the problem with new cars.
I once tried to help the owner of a new XJ8 who
said the car hit a small bump and died.
Turning the key did nothing, and we could not even
push the car to the side of the road, as it would not shift out of park.
Something to do with the alarm I suspect.

So here is a guy with a new $60,000.00? car that has to be towed
after hitting a small bump?

Seems like we are going in the wrong direction…

Rich, Brett, et al.
I have just finished a conversation with the service rep at the
dealer I took
my car to. The check engine light was triggered by a stuck EGR
valve. I had
considered this and I knew the early valves (before mid year
1997) were prone
to sticking and causing a rich running condition. I took the car to the
dealer because I could not diagnose the electrical problem
indicated by the
transmission MIL. It turns out that any time the car is in motion and

engine is not firing (like when it has just died do to a stuck EGR) the

and I am only out the bill for the wrecker service to haul the
car up to the
dealer.
The interesting part of all this is that none of the error codes
or diagnostic
procedures listed by alldata mentioned the EGR valve. I knew of
the sticking
problems by reading the technical advices listed by alldata.
Rich, I would run your car by the dealer and ask them to check
the manufacture
date of your EGR and replace it if it is one of the earlier ones.
The dealer
should replace it at no charge.

Rich,
On the older cars, its been known that a long downhill
run with your foot off the gas will have the ECU
basically shut off the engine to prevent pollution and add
engine braking…and the engine cools off enough to trigger
a coolant temp sensor alarm.

On the older cars, the code would be set if the temp changed
faster than the ECU thought it should…

In order to find out or clear a code, you need the scan tool.
pulling the battery or fuses is a bad idea on an OBD2 car.

I think a scan tool that uses a laptop computer would be handy
just to know if the code was serious to the point the car
needed immediate service.
Its also handy to have to clear any odd code like the
coolant temp sensor code, a miss code, etc.
My wife had a saturn that would set a code on a cool moist
morning sometimes, and the dealers said it was common and just
cleared the code.
She sold the car because she did not want to go through all
the hassle every month to get the light to go out…

Of course, your problem could be something else, and could
be serious, but with the fantastic obd2 system, you have no
idea if the engine is on fire, or had a temporary miss…

This morning my '97 X300 XJR stumbled and missed for a couple of
seconds and the check engine light came on momentarily. I’d just
come down a long hill in 3rd and had upshifted to 4th… after
she shifted I accelerated fairly gently and she started missing
and losing power (maybe just a hairball?) This lasted no more
than 2-3 seconds.

After that everything returned to more or less normal, although
it subjectively felt like it might be running a little rough for
a few miles. (This might have just been
post-check-engine-light-stress-syndrome)

Is there a quick way to read any code that might have been
stored without diagnostic gear? I’m planning to bring her to the
dealer, but if it looks minor I’d like to wait until next week…
