Hi gang, I am in a bad spot and in need of some advice.  I do not know
anything about cars, but need some input.  My 99 olds intrigue today
had the service engine light come on.  When I’m going slow it is a on
constant but on a straight away it flashes.  It seems to be running
slightly rougher and when I hit the gas the rpm jump, but the car
doesnt’ accerlate like it should..  What might be wrong with it.  I
don’t want to be an easy mark when I go to the shop tomorrow.  Any
input would be greatly appreciated.  Thanks
