Running rich........... I know this maybe a stupid question but I have been reading about people on here saying they are running lean or rich all the time. What are the tell tell signs if any that I could use to tell me if my car is running rich, besides using like ls1 edit or something.

Re: Running rich........... Usually you should only worry about runnin' lean/rich with lots of mods and LS1 edit. If you run a mostly stock set-up with stock pcm tuning you will get a ses light when a/f ratio's get off track. This is what it is designed to do, warn owner of drivability/emission problem. That goes for all light duty vehicles 1996 & newer that must have E.P.A. mandated OBD II powertrain control systems. If a/f is off either you will know running wise or pcm will let you know with that old service engine soon <img border="0" alt="[Banging Head]" title="" src="graemlins/gr_banghead.gif" /> light.
Re: Running rich........... Well AutoTap is the only certian way, but if you are running rich you should be able to smell gas when you go WOT. There will also be a light tannish brown color on your exhaust tips if your running rich.

Re: Running rich........... 220 miles a tank!? You lucky bastard! I get around 170 with my 2002 M6 doing a 50/50 mix of highway/city driving. Granted I like to get on it alot but if Im not running rich now I probably will be with my new hooker LT's right? Time to visit the dyno shop or just buy a MAFT?
