Fueling & Injection - running very rich waht can i do?

hey guys, i got 28,000 miles on my car, and have noticed the thing is running really rich, anyone have any ideas how to fix this, i was thinking maybe replace the 2 o2 sensors in the front but waht do you guys think? i also have the mods listed in my sig, if that has anything to do with it

How do you know it's running rich?

Someone told me i am, lots of buildup on my exuast tips, and when i put my finger on it and smell it it smells like gas.. i have had numerous people tell me i am running rich

at least get auto tap on it to see what your AF ratio is to determin if you really are running rich.

where can i get it scanned? does anywhere do it like autozone or anything?

"and when i put my finger on it and smell it it smells like gas.. i have had numerous people tell me i am running rich"

When you put your finger on it you're not at wide open throttle and thus you're operating in closed loop (if not, you'll have a check engine light.) When operating in closed loop your mixture is held at 14.7:1.

You have no idea if you're running lean or rich at WOT. You need to at least check the S1 O2 sensors at WOT with a diagnostic scanner to get an idea of your WOT mixture. Get autotap (it's software that is used with a laptop computer) or find someone who has it. Or, if you might talk someone with a Tech II (what your local GM dealer has) to take a ride with you.
