Had the following done at Nissan , after going in because my car kept stalling - all lights would go on or at least the ‘Service Engine’ light, then car would die even on highway at high speed.
-clean entire fuel injection system
- new belts - everywhere
-Alternator
- O2 sensors
- Battery
BUT…5 months later now…my car is stalling again - Brake and Battery light went on, car sputtered but kept going until lights went off. Then later, Service Engine light went on and more stuttering.
SO, Was all that work necessary?
Fuel injection cleaning when I always put Super Gas in? Brakes within a year of new ones?
How do I know if they even completed it?
AND, what could be causing the sputtering now?
I don’t know about the earlier work, but ask them to scan the computer for an ‘ignition coil’ code. That could be the cause of the current sputtering.
That CEL (check engine light aka service engine light) is just a kid in class waving her hand trying to get you attention because she has the answer. You need to have the codes read. Some places will read them for FREE. Try Autozone or Advanced Auto Parts. Get the exact code (like P0123) not just their translation into English and post it back here.
