Cadillac 1987 125,000 4.1L 250ci v8
my question is I just got new exhaust sys. And the mechanic said there is something wrong because during intial start up the exhaust temp with so high it was making the new pipes turn blue and was making the cat. Glow red- also the engine has been idling very high and would make the engine surge in stop and go driving? We shut off and couple mins. Later and it was fine.
Is there something wrong with egr or the idle please help?
