Bad gas doesn’t combust evenly – which can cause your engine to sputter or ping. Listen to your car both at idle and while driving at moderate speeds. These noises aren’t the smoking gun on their own, because they can also be caused by a bad fuel filter. 3: Stalling While Driving.

1. Bad gasoline in your tank can cause problems in a car engine, like knocking and pinging, engine misfire, rough idling and stalling, according to AA1Car.com. The problems will typically involve how the car drives and its emissions.
2. Problems occur when your fuel tank is overfilled and/or gas flows into the EVAP line. A defective refuel and/or fuel cutoff valve prevents fuel from flowing and the refuel valve triggers the gas pump to stop, causing the car to stall. Brought to you by Leaf Group.

Can A Bad Gas Cap Cause Stalling

This problem has been going on for a while, it comes and goes. The truck will start stalling out, sputtering along, then pick right back up. It is like the engine is being choked for gas. It never totally fails, I just lose all engine power for a second or two, then it picks back up. Then, the check engine light will turn on.

I thought the light might be for a gas cap, so I checked that first. Unscrewed the gap and hear a very noticeable “whoosh” air noise, like air getting sucked into the gas tank. After I adjusted the gas cap, the truck starts working as normal, runs great. For a couple weeks or so. Then the same problem. And the same fix has always worked as well - the gas cap trick, thus far, has worked every time (about five times).

Can A Bad Gas Cap Make A Car Stall

I took it to a mechanic and they said the codes are for the throttle and I need a new throttle body for $1500 freakin dollars. I don’t doubt the throttle could probably use replacin, but I don’t think that’s is what is causing this issue. If the throttle was the problem, it doesn’t seem like it would be a problem that comes and goes. And why does the gas cap fix work?

Things I have replaced in the few years - fuel filter about a year ago, air filter recently, evap, O2, cat, timing belt, water pump, gas cap (about a month ago). Needless to say, I got a lot of $ into it. Think it could be fuel pump?
