Heavy Gas smaell in the cabin, Cyl 1 error even after replacing Coils and Plugs
Hi All,
I would appreciate any guidance on these issues. I have a heavy gas smell in the cabin after filling the tank from time to time. I was reading that it could be the injectors or the HPFP. Any thoughts?? Another question is i have had a Cyl 1 error, I've already changed the spark plugs and the Coils. Anything else I should be concerned with or look at before i take it in to a shop? |

Do you notice a fuel odor OUTSIDE the vehicle after filling tank, or when walking past the rear of the car, and if so, at WHAT location, & under WHAT conditions? If the Tank vent that vents air from the tank as fuel is filled is NOT working properly, of if you have a leaky gasket on the top of the tank, or other tank fault, fuel can spill or escape from the tank. You might remove the rear seat cushion and inspect the tank seals on either side for any sign of fuel which has leaked out. [2] What "cylinder 1 error" do you have? What other Fault Codes do you have saved in the DME? What Scan Tool or Software are you using to read those codes? George |

a leak in the evap system will explain both of those usually. you have fuel vapors leaking from the tank and the engine sucking in unmetered air.
a smoke test will likely reveal your leak. |

that's probably a waste.
the evap system literally has lines that run from the rear seat bench to the engine, so it can be anywhere under the car. it's purpose is to feed the accumulated fuel vapors into the engine to be burned, so they are not released to atmosphere. you smell it most after filling the car because filling the tank pushed a whole bunch of vapor out of the system because it has a leak. |

If you had a wet spark plug, it’s a sticking injector. Is there any white smoke coming out the exhaust on cold start?
