check engine light

I don't know if this works in the newer cars, but in the older ones (my 
'88) there's a fuse you can trip which will read out the engine code for 
you. I think I found the fuse number in the Bentley (which I don't have 
with me; I'm at work). A 5 amp, if I remember. 

It's been a while since I've done this (I used to have to do it on an 
annual basis), but as I recall the dash light displayed the code by 
blinking a series of times. I watched the display for a while to make sure 
I had the right sequence of flashes, then I looked the code up on an 
error list. 

In my case it was always the O2 sensor, and since I've finally figured out
why I'm toasting the sensor, I now ignore my check engine light (_most_ of 
the time &:-)). Sorry to not be more helpful.

'88 80Q currently with check engine light on and a slightly roasted O2 
sensor from driving race gas; I'll replace the sensor when the engine 
management gets _really_ obnoxious...

Det beror inte på vem du är; det beror bara på vad du gör.
