I don't know either but as long as you job isn't measuring the the low pressure vacuum created by someone's backside it doesn't seem like a bad job lol. Does anyone have any scientific proof on this topic? My question now is why then, when I was smoking my first cigar in my car the other night (going down the road) the smoke was sucked out of the window? I had the window open about and inch in this situation though, as opposed to all of the way. What do you think 93must?

I owned an 89 LX 5.0 new back in 89. I put 46k on the car and never smelled exhaust like this at any time. It wouldn't bother me now except it is enough to make me dizzy and my clothes smell bad after a 10 mile ride with the windows down. I just want to know how to adjust the richness if it is adjustable.

Wish I knew more about it. Like when it started smelling? The smell can only be coming from one place and that is your exhaust!
I would bet money it is from your dumps. Thats why they put the exhaust out the back!




Oh and dont smoke in your car![sm=shootshoot.gif]

When I got my 91 gt it smelled real bad it had dumps so I got tail pipes put on help but still smelled bad at a stop, come to find out I had a vac leak on top of intake fixed that all better now. Don't know if that will help you or not but that fixed mine.

How would a vac leak cause the inside of your car to smell like exhaust?

I too am curious on this.

And my reason for smoking was a good one, but I really don't want to talk about it. The guy who I bought it from was a f*cking chain smoker though [:'(], so I don't think it made a difference anyway.

have you looked at your entire exhaust from the headers back? could have an exhaust leak going from your headers to the midpipe, or a rusted through part of your exhaust or something like that. if it was at the junction of your headers and h/x pipe that may make sense because it would be in front of you and could also come in through your interior fairly easily
