Check engine light

[Bryan Altier]

Jim, Welcome to the loose connection club. We have the same coach and it was
doing the same thing. We even called the Detroit dealer out on a weekend to see
what was going on and when he got there I fired the 8V up and ran great. When I
got back home I had my detroit dealer look at it and they had to get out the old
diagnostic equipment to find that I had a loose connection on one bank. They
cleaned and made sure everything was tight and we have not had any further
problem.

I have alway had the check engine light come on going down hills but as soon as
I touch the fuel pedal it goes out. It does not leave a code and the dealer
thinks that this is a problem with the light system itself rather that the
engine.

Hope this helps....

I have a 1988 BB wbwl with 8v92 DDEC while riding along at 62- 65 mph
1700rpm my check engine light stop engine lights come on along with
buzzer. All guages are in operating order and are in their normal
ranges. Sometimes when I turn on the aux fan the light and buzzer go
off. recently the coach decides that it needs a break and forces me to
stop (engine stopping) momentarly turn key off wait not more than five
minutes the start the coach and drive off. On a 265 mile trip this
happen two to three times......

Any Ideas??
