The code P0422 per oBD diagnostic is evap emission control has little leak. Where is that evap emission control located?

you have something allowing the gas fumes to leak out of your emission system is what code po422 means if you replaced your gas cap and this code came back after resetting your check engine light then some where in the vent line between the fuel tank and the intake there is a leak that is allowing the gas tank to depressurize which will turn on the light and cause your cars ecm or computer to go into (limp mode) this is a preset program which allows the driveline to operate at a non optimum setting or diagnostic setting meaning it will get lousy gas mileage until repairs are made and the problem is fixed as far as being safe to drive it could be very dangerous depending on how bad the leak is and weather the car has exhaust leaks also you are dealing with gas fumes closed in say like parking in a garage where these fumes can build up it can be very dangerous if enough fumes build up in such a instance out in the open not very bad at all

Ok this only started once it got cold out. when I go and start my car to warm up there is an overwhelming smell of gas inside and out. It gets better as I drive but as soon as I have to start at a light or...

Firstly stop driving your car until fixed !! You may have a cracked fuel line or split fuel line. Your problem seems worse at lights because you are stationary with no air flow through your car to blow the fumes away. It is dangerous to drive as it is. All you need is a spark from a cigarette etc. Any doubt get it towed to a garage .

The smell i'm having is not the raw gas smell , it smells exhaust fumes getting in the car. i checked for exhaust leaks buut had none

if inded the smell of exhaust is getting into your car i would suggest not driving it until it is properly checked by a licensed meachanic. it could be entering through your heater/AC blower and in return be fatal if left untouched for a period of time

Fumes escaping from ac vents inside vehicle while driving and leaves a film residue on inside of windshield whenever the heat or defrost are used.

Hello dedunwoodie.
Your heater core is beginning to leak coolant.
As the fan blows through it it is picking up the liquid and depositing it on your windshield.
It will need to be replaced to solve your problem.

Radiator coolant fumes inside cabin

There is a chance you may have an engine bay coolant leak and the fumes are being drawn in through the heater ductwork so verify that first.
Coolant fumes inside usually come from a leaking heater core. The heater core is like a small radiator inside your vehicle that gives off heat.
Problems like this arise from coolant that has not been flushed and creates an electrolysis that eats away at the material causing a leak.
This is not a job for a do it yourself guy(or girl). A pro could easily spend 5 to 7 hours changing this one.
Make sure whoever does this repair flushes the system.

Gas smell in 97 q45

You need to bring the vehicle back to the garage that worked on it asap and have them check it out. It sounds like they are responsible since the gas fumes started when the fuel was changed. Most are inside the gas tank. There is a lock ring on the tank w/ a gasket that must be removed for access. Chances are they either didn't tighten the lock ring sufficiently, or the gasket is crimped or out of place, allowing the fumes to escape. Leave the car outside until you bring it to the garage, as fumes can collect if parked inside and cause an explosion it a spark is present-like turning on a light switch or starting the car. If the reason for the fumes is as I described, the garage should fix it at no extra charge to you.

Fuel Smell in Car

I had this problem.  The fuel pressure regulator was leaking gas.  $50-$100 for a replacement.  It is not safe to drive around if you have a gas leak - could start a fire. Look under the hood to find where the gas is leaking, should be easy to see/smell when the car is running.  If you cannot find it, take it in to a shop right away.
