1992 Buick Roadmaster with the 5.7L V8 engine
I have a 1992 Buick Roadmaster with the 5.7L V8 engine. The problem that
I’ve been having with it is the SES comes on whenever I back off the gas
when doing more that 60mph. The car still runs smoothly, drives well but
the SES comes on and stays on. Once I turn the car off, then back on the
SES clears and the car runs fine still. Anyone have any ideas on where to
start trouble shooting this issue?
