My car is idling most of the time at 13.5-14.0, I know the optimal a/f ratio is 14.7, so I was wondering if by having my car idling at those numbers if that's a real concern? There is also the ever present scent of gas coming from my car, could the fact that it's running a little rich be the cause of this smell?

That 2 me honesty isn't rich..I mean its not stoich..but even still.you really shouldn't be smelling gas if it infact is at those levels..ever think of an exhaust leak? Or fuel leak for that matter? Most cars are tune end up between mid 13s to mid 14s for idle..I try 2 shoot for 14.7-15.0 but don't make it a big deal 2..some cars idle happier at a slightly richer mixture..
I honestly wouldn't worry about it..airfuel wise.now gas smell wise.start looking..there's something going on somewhere.

you should be in the 14s on crusing, 12s in boost, and 15-16ish on idle. so yea, your running more fuel than you need.miss my turbo cb7

All depends on tune, gas octane, and climate conditions.Originally posted by quickangel93 View Post
I can run up to 13's in boost with no detonation, 15's in cruise, and 12 at idle.
Also a major factor in idle mixture is the ECT value.
When I first start my car cold, its 9.7ish
