Q: Issue with my car stalling - 2003 Chevrolet Malibu

asked by on

i have a 03 malibu and i have noticed that it has been stalling a lot i got it checked out and they said its the catalytic converter but when I had to get my alternator and battery changed my check engine light went off for about a month and then it came back on and that's when my car started to die a lot and now its worse. sometimes when I start the car it acts like its going to kill but it doesn't but a few mintues later it kills so I have to mess with the fuses in order for it start back up. I have to let the car sit for a while while running in order for the temperature meter to get about halfway before moving the car if not it kills but sometimes when I do that it still kills. I noticed when I first got the car that no matter how much gas I put in the car the needle never goes past the second notch after a half a tank. I really don't know what is going on with the car.

My car has 171200 miles.
My car has an automatic transmission.

Hello, thanks for writing in. Replacing the battery reset the diagnostic code retention, so if a problem code for catalytic converter failure is present, that is a persistent problem, and requires attention. The sluggish performance you mentions, and your advanced mileage are also indicators for a failing cat.

I would recommend having a catalytic converter replacement service completed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

The malfunctioning gas gauge issue is likely the fuel pump/fuel level sending unit. There is a technical service bulletin from Chevy for the "inaccurate gauge" issue (#137204). Check with your Chevrolet dealer for this repair in particular.
