For about the last 4 months, I've had a moderate-strong odor from within my vehicle. I beleive the odor is strongest in the back of the car. I can get a good whiff when I roll my windows down and the air pushes the odor to the front of the car. I can also get a good whiff when I load groceries into the trunk. I think it gets stronger if I do a lot of stop-and-go driving, as opposed to highway miles. The odor is more noticable in warm weather, but I don't think it's dependant upon the level of gas in the tank.

I drive a 97 camaro with 44,000 miles. I've taken it to the service shop three times, but they have not been able to detect anything but a few pinhole leaks in the neck of the tank. I've had the tank replaced, but there haven't been any improvements.

The car was in the body shop about 9 months ago when I was in an accident, but the odor didn't pop up until 4 months ago. This could be a residual effect of the accident, but all of the damage was limited to the left side of the vehicle (almost no internal damage).

Any suggestions?

Seriously, does it smell like boiled eggs or fart? You need to replace the oxygen sensor. My wife's '98 Mitsubishi Diamante did the same thing and I replaced the oxygen sensor and it corrected the problem!

Please let me rephrase that. If it's immitting a foul, sulphur-like odor, then it's definately your oxygen sensor.

And do it soon. A bad ox sensor will eventually trash the converter.

If you replace that oxygen sensor and it doesn't fix it, try getting another MAF sensor for the car....Fixed mine.
