Car shakes aggressively while gassing up!!
Hey guys,
I've a friend who's not on the forum and owns a 1LT facing some issues. Was wondering if anyone here would possibly know whats going on. He claims his car drives and idles smooth and fine, however when and ONLY when gassing up, he experiences rough idling and his car shakes from side to side rather aggressively. Any idea what it could be? Haven't taken it to the dealership as yet and trying to avoid doing so because unfortunately our lame dealership would most probably say "this is normal" even if you placed a burning car in front of them. Would appreciate your expert opinions. Best regards and have a nice day!! |

For starters, it's against the law to fill up a vehicle in a lot of states while the engine is running, so you might want to ask your buddy to double check the local laws on that one. Second, I wouldn't be surprised if it was some sort of breaking of a vacuum that is causing the issue.

It could very well be unhappy with the seal breaking the vapor recovery system in the gas tank..
Also, as pointed out above.. It's inadvisable and probably illegal to fill up your gas tank while the engine is running. EDIT -- I see you're listed as being in Dubai.. I don't know what the laws are there about leaving an engine idling while gassing up, but you might want to check that.. Here in the USA, it's illegal. |

It might not be illegal in Dubai to fill up with the engine on. Or its possible that he meant accelerating in stead of "gassing up".

Exactly.... If the gas cap is loose, it will trigger a check engine light, that's common in all cars these days. So I would assume if engine running/refilling, you're messing with the whole fuel system. Stop doing that, says common sense.....LOL |

You said, "He claims his car drives and idles smooth and fine." idles rough and shakes while "gassing up"....We're guessing that you mean "re-fueling" or "filling up" the car with gas.
If this rough running is because your friend leaves the car running while filling the tank with gas...Tell him to shut it off before re-fueling....End of problem. |
