I am sorry your having this problem

how low was the oil and how much did you add ?

was the spark plugs changed to correct this stalling issue ?
is the coolant low ?

I just added 5 quarts and I just did spark plug wires. Did not add coolant yet
Customer: replied 2 years ago.
Oil was very low
Expert:  Gary replied 2 years ago.

how much smoke is coming out of the exhaust ?

and it is running like one of the cylinders is dead ?

Customer: replied 2 years ago.
A lot of smoke and nit sure about th cylinder but car is constantly stalling mostly at intersections when coming to a stop
Customer: replied 2 years ago.
Car hesitates when stopped then stalls
Expert:  Gary replied 2 years ago.

the smoke bothers me as usually with alot of smoke out the tail pipe and coolant being low the issue is usually bad head gaskets

if you remove all of the spark plugs right now do any show wet with coolant on them at all ?

Customer: replied 2 years ago.
Unfortunately I don't have the necessary tools right now to take out spark plugs so unknown

How much do head gaskets cost to replace
Expert:  Gary replied 2 years ago.

Customer: replied 2 years ago.
Do they run cheaper anywhere?
Expert:  Gary replied 2 years ago.

you can try a non dealer and call around and get some quotes and see how cheap you can find a shop to do this for you
