can you tell me if this problem is with a idle air valves control on this Cadillac Seville sls 1996
check for vacum leak
If the vehicle all the sudden just dies (stalls out) or sputters -R Diesel
Could be EGR valve sticking open or dirty at an idling condition or hesitates when accelerating.
Not a question. Operator error.
Needs crankshaft sensor and or camshaft sensor
trade it in, or sew whoever sold it to you as a lemon, unless you bought new or as is.ORget it inspected and try to find out whats wrong with it
you may have a vacuum leak
there is a number of things that could cause this, if your check light is on it's prob a sensor. most of the time it's a mass air flow or O2 sensor.
When my 2002 SC2 sputters, stalls, "Service Engine" light comes on, I dump a can of injector cleaner in the tank and it runs fine and the light goes out. Can't say for sure that's your problem, but it is a small enough investment to try it out. Good Luck.
You have to change the mass flow sensor
your exhaust is probly stopped up
Could be your oil is old or too thick. I would try a tune-up and oil change before looking elsewhere.
