Re: car smells like gas

did you get your computer reflashed to accept the 24lbs. injectors? if not that may be the problem. stock lbs./hr. is 19lbs. make sure your computer was reflashed to accept them.

Re: car smells like gas

is it smell like fuel, like raw gasoline...or does it smell like exhaust. Usually you can hear and exhaust leak.

There is a gas tank vent located underneath your car infront of gastank that sometimes need replaced, that could cause a raw fuel smell.

An exhaust leak usually has black carbon streaks where it is leaking from....and a muffler shop should be able to check it for leaks for free if you can't get under the car.

Re: car smells like gas

thankz for the info....i have a custom chip so im pretty sure they did program everything for the bigger injectors....it is more like exhaust smell but it smells bad as it comes from the tail pipes....one time my spark plugs filed out and it is feeling a lil sluggish "boggin down a lil" so ima change them out again....
