High ideling

Michael Cope

Asked by Jul 16, 2016 at 04:18 PM about the 1997 Cadillac DeVille

Question type: Maintenance & Repair

When I start up my Cadillac deville right
when it turns over, it jumps to the high revs
until it backfires and dies out. I replaced
the mass air flow sensor and reset the
onboard computer but it still does the
same thing

try looking for vacuum leaks. a vac leak will cause idle problems and could make the car die.


Sounds like there is a serious vaccuam leak some where. Check vaccuam hoses

Some people have told me it could be the idle air control. Does anybody else think that.?

Michael Cope

when I ran the diagnostics it came up as some wiring or mass air flow sensor
