Doesn't seem like a fuel system issue. Probably an issue with the idle air control (valve or solenoid) or a sensor, possibly the throttle position sensor, that is not sending the correct signal to the computer. Try downloading trouble codes, even if the check engine is not on. There could be a pending code. You may also be dealing with a bad wire or connector.
I have a 2013 Chevy Sonic. For the last 5 months, my car has stalled during driving and when in idle or when I stop at red light and stop signs. Also, it fails to turn over after putting gas. It will turn over fine, but it won't stay on. I've had my fuel injector cleaned and inspected. I've had my O2 sensor replaced as well. Do you have any ideas what this could be?
The engine light came on and showed the check emission system message. I went to AutoZone to check the code. It showed P0420. They said it’s the Catalytic Converter and Exhaust Flange Gasket. I just had my emissions inspection about two weeks ago, and it passed. I filled up with gas yesterday. Is there anything that would cause this that would correct itself? I’m a single mom and want to check anything I can before I spend the money to take it to the shop.
I just replaced my 1970 mustang's 302 valve covers, intake manifold and upgraded from 2 barrel to 4 barrel carburetor. In doing so, I had to lift the distributor up a bit in order to install the manifold. Would that throw the timing off? The engine cranks and puffs and seems to want to start but simply won't. Any thoughts?
