I'm on the highway going up hills. Everytime I drive my truck up a hill on
the high way the service engine light comes on. Driving on a flat area
doesn't make the light come on. So when i finally get to where i'm going and
pull over, rev the engine for 10 or 15 seconds the light goes off. What is
this telling me or what could be going wrong? I don't hear/see or feel any
thing unusal when this happens. I tried driving it in the city going up
hills and such, but it seems to be working perfectly fine even when the
light is on. Anyway, should i be concerned about this or what? Any Help
will be greatful. Thanks
another thing i noticed is the light comes on when the engine/tranny changes
from 4th gear to 3rd gear going up the hill. that's when the light starts
flashing. I'll take it to autozone or what have you and see what the
computer says. Right now the light is off, will they still be able to read
it from 3 weeks ago. it's been going on for 3 weeks now. Thanks for all the
info. i'll do that tomorrow and see what i come up with.
