Sounds like an exhaust leak either at manifold or collector pipe. Exhaust is being sucked in through fresh air intake for hvac system. Must scan to determine what code is setting check engine light.

SOURCE: Check engine light is on. EVAP small leak

You need to check the purge and vent solenoids for proper operation. You need to check the pressure sensor for out of range ( defective ). You need to check the filler neck for cracks and make sure the clamps are tight. You need to check the vapor lines for loose fit. I've seen at the charcoal cannister where the lines connect it may not be on strait. A smok test will reveal this if its not sealing. You may have a leaking rollover valve or fuel pump seal on top of the tank. You may just have a vacuum leak under the hood, These trucks have an Evap management valve also that can be leaking or out of specs. Look on the emmisions lable or vacuum chart under the hood. This will show you the underhood components.

The reason why the service light come on because it is a hard code

SOURCE: I have 2008 Ford Escape

this is an obd2 trouble code table, it can help you understand the meaning of code,
and for p0455:
A code p0455 most likely means one or more of the following has happened:
A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
Other leak or damaged piece in EVAP system
Possible Solutions:
With a p0455, the most common repair is to:
Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
Otherwise, replace the gas cap, and/or
Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary
for p0457:
The only way a P0457 can set by itself is if the gas cap is left loose, assuming the van is in working order. when the engine controller sees a large increase in fuel level it knows you put some in the tank, and it runs the evaporative emissions system test to see if the system is sealed. If it sees a large leak it knows the cap was left off and sets the P0457. If you are positive the cap wasn't left even a little bit loose you may have a leak back there. It could be in the filler neck, from the tank to the evaporative emissions canisters just behind the subframe on the left side, and from there on up to the right front corner of the engine compartment where the purge solenoid is. If you don't see any leaks you probably have a bad NVLD, the unit that checks the system for leaks. This is probably what you are going to find.
The pressure or vacuum in the fuel tank when you remove the cap tells me that the system probably is sealed and has no leaks. Many times there will either be a little bit of pressure or vacuum in the tank, and it's perfectly normal.
The fuel gauge being innaccurate is either the sending unit or a problem with the pump module itself. there were some problems with some of the pump modules that allowed continuity between two of the terminals in the fuel pump connector and it caused the gauge to be wrong. You will probably end up needing to replace the fuel pump assembly for the gauge issue.
hope help.

1994 dodge caravan has bad exhaust smell and sometimes feels like not enough gas getting to motor and will just shuts off

it must be diagnosed with a diagnostic computer; there are a vast number of things which could be the problem and the only way to get an idea of where to look is to know which codes are set.

I smell gas but i'm not lossing any.

My first question is - is the check engine light on when you are driving ?
You could have a leaking injector which could be causing fuel to escape thru the exhaust. You could also have a leak in the vent system for the gas tank.
The need for coolant and oil if no leaks are visible usually means the engine is burning the fluids because of an internal engine leak or head gasket problem.

1999 gmc suburban-smoke comes out exhaust and smells like gasoline

If the check engine light is not on, I would check the fuel pressure regulator and for problems with the fuel return line.
If you have a leaking injector you should get a check engine light and code for a cylinder miss.

My 2000 ford focus dohc stalls n loosing power wile driveing then stalls n u have strong exusust smells

Hello, You may benefit from a FREE scan of your car at Autozone, Advance, or Oreily autoparts stores. If your problem started after getting some gasoline, this does sound alot like bad gas.

The self Diagnostic computer in your car should make the "Check Engine" light activate if it is a Mechanical defect. There is a part called a "Throttle Position Sensor" which sets the timing and fuel flow for the conditions the engine needs to run at. These settings change almost instantaneously and a failing part could make it work intermittently.

The balance of the Engine Management System would generate a traceable Code. If the exhaust smells like Sulfur, there is usually too mush gas. A sweet exhaust smell indicates an Internal Antifreeze leak into the engine head, and your Antifreeze level will draw down. Stale gas has a Metallic smell like steel melting in a Foundry oven.

If the Diagnostic tests do not confirm anything, then try getting a fuel sample done and have the Fuel filter changed at the same time. There is pressure in the system and you may need to bleed off the pressure before the Fuel filter will come off. This can be a messy job. There are also tools specially made to decouple the filter.

That is about all I can recommend at this time.

My gas mileage has decreased quite a bit. Sometimes I can smell gas when I get out of my car, and occasionally inside it. I couldn't see any obvious leaks, so I took it in and the mechanic couldn't...

not sure on this amerian car but most vehicles have a inspection cover over the top of the fuel tank under the back seat and i think you may be leaking on the flexible piece rubber tuber around this area

I smell gas a little in my 1990 ford taurus any idea where to start looking???

First, take a quick sniff of the exhaust when the engine is idling. If you smell gas there, check your spark plugs and wires to eliminate misfires, then check for leaky fuel injectors (leaking excess fuel into a cylinder).

If the exhaust smells normal, you'll need to inspect the fuel delivery system. The most probable place for a leak would be the fuel lines under the car; it's old enough that a line could be rusted through and have a pinhole leak somewhere. If you suspect a spot but want to verify it by turning on the engine to pressurize the line, be sure to wear safety goggles. You don't want gasoline sprayed in your eyes.
