maybe someone can suggest something to help this.
i have a smell of gas whenever the car is on, as if coming from exhaust, i have no cats, no egr,no smog, however i wonder if the charcoal canister will help if i change it. i have timing set to 10degrees and i don't think that it is an issue, but i could be wrong. anyone?? also my idle is never right and i have cleaned and replaced my iac, and map, coolant is good so its not like the ect is ready air in system.also both the ect and temp gauge sensor have been replaced as well. i don't know if this could be related to my gas smell because if the car is running rich of course i would think i am gonna get a smell of gas from the exhaust. and if it were one of my o2 sensors idk if it would make a difference to change them. i don't have a check engine light on or anything.

If it smells like raw gas then 95.0% of the time you have a leak somewhere. But do you know how rich you tune is? For all you know its really fat. I would check over the fuel system to make sure there is zero leaks. Do you have anyone with a spare wideband? Also check the rails you never know if under a high load your injector might be leeking, and only smelling it after the fact! As far as the check engine light not coming on, are you sure that the light bulb is good? I would put it on a scaner to find out!

since it is an exhaust/gasoline smell and i don't see any leaks under the hood or under carriage i can only assume that it is a rich/lean issue. the fpr sounds like that could be a possiblity. i'll look into it. but i will also double check my injectors and rails. thanx guys

CHECK YOUR OIL!!!!!!!!! I had a bad ground on the computer and it caused the injector duration to stay open way too long. It thinned down the oil very quickly.

it is normal for cars with no cats to smell like gas. If everything checks out (no visible fuel leaks from lines, fittings, injector o-rings, if the gas cap sealing right, if the line to the evap canister is not leaking, I would not worry about it. If you have an injector that is stuck open you might get raw fuel come out of your exhaust, specially when you first start the car up.
