You need a special injector return flow tool, you can actally make it yourself, info on the internet, normal symptoms are increase in consumption, smoke from exhaust (should be black). If you have a good ear there will be a metalic sound coming from the rocker cover near the injector.

2008 Chevy cobalt 2.2 l 133,324 miles. It just started to hesitate to start and smells like raw gas. What could it be?


Hi Jesse, IM AL the owner of Big As Auto Repair.

Jesse, if you are smelling "Raw Gas" then this is a sign of a gas leak or an injector stuck open flooding the system.
Start the engine and check for fuel leaking from the injectors sometimes and injector will leak externally. Also check for fuel leaks around the fuel line and fuel rail, also check under the vehicle, the fuel lie, tank, filler tube. The Internal Injector leak can only be checked after removal of the fuel rail (engine off). With the fuel rail in your hand have someone turn the key on (engine off) it should be a spray like pattern from each injector and no drips after the spray. NOTE: This should be checked only after there were no other issues found with the first issues I talked about. Hope this helps and please visit my auto-repair-website http://www.bigasautorepair.com/

Rough idle and smells like gas when driven


When checking for Vacuum leaks, did you use a water spray bottle on seams and vacuum lines and EGR pod?(engine running)

Check for air leaks in exhaust before O2 sensors. O2 thinks its running lean from air leak in exhaust header and enrichens fuel charge.

Fuel injectors dirty, not closing tight. Switch injectors to other bank and see if Error Code moves to relocated injectors.

Bad spark plugs, check if you have fuel runners in your intake.

Gas leak in engine compartment.


Without looking at it, If there is raw fuel anywhere up top this is what i would do:
1. check rubber fuel lines on the intake. easy fix if leaking
2. check or replace the fuel injector o-rings they are $3.00 per set easy fix.
3. check cold start injector for fuel leak also easy fix

If no fuel leaks can be found in lines i would go straight for the injector seals but in noway would i let this stop me from buying the car if thats all thats wrong. even if an injector is cracked it is under $80.00 fix. here is a link showing the injector and o-ring position http://www.oreillyauto.com/site/c/search/Fuel+Injector/02521/C0024.oap?model=Legacy&vi=1269996&year=1997&make=Subaru

My 99 cadi has a gas smell comming into the cabin


You might check for leaks starting from the tank to the injectors. If you do have a leak then your more likely to find it while its running. Injectors need pressure to run. With pressure, gas will come from the leak if u have one. If you dont have a leak then your car could be burning a little rich causing a gas smell. An o2 sensor could also be the problem.

HI I have a 2004 Mazda RX8 and I smell GAS coming from the rear drivers side. I can smell it when I am inside the car for a bit..it is most noticeable after I park the car. I checked the gas cap to make...


I had the same problem last year with my rx8, I smelt gas inside the cabin, and every time I parked in the garage it would smell strongly of gas. I tried injector cleaner and everything, but nothing helped. About 4 months after i started to notice the smell, one of my fuel injectors blew, I believe the small was coming from the crack in it, I would suggest you get you injectors checked, After the blow, I got it fixed, they rebuilt the injector for about $300 cad. and it runs great now,

Hoped this helps

Why does my car smell like gas & uses way too much gas and is leaking gas on my engine out of a line?


I don't know if your stating that gas is leaking on your engine but anyways....other than the bad syntax in your sentence. You may have leaky injectors and there maybe too much fuel getting into your combustion chamber and getting stuck around the catalytic converter which will give you really bad gas mileage, smell like fuel and destroy you Cat.Converter. Start with injectors to see if they are leaking and check all fuel lines thoroughly. Also check your charcoal canister (black canister on the firewall) to see if its broken, cracked or leaking anything. If its very strong. Check near the tank itself. If you ever see fuel on the ground when you fill your tank, you may have a torn line at the tank or the seal around the gas tanks fuel sending unit is leaking is leaking. Good luck Plz rate

Check to see if your filler pipe is rusted(The pipe where you put gas in). Do you smell gas stronger when you fill up your tank?
