Still Pig Rich...

Hey all, i was wondering if there are any other ways to lean out my 2g other than the MAS screw? I did that and even removed one of the honeycomb sections (that helped), but my car is still running pig rich. THis seemed to start after I installed my downpipe.... I have no money for SAFC or any tuning work- can i do it in a dorm parking lot?

btw.. im running the stock T25 with stock injectors and fuel pump.

Do you have any boost leaks? Those will make you run rich.

**meanNgreenTSi** · January 29th, 2006, 04:49 PM

good idea, any place that they would be common. Ill check, although it still pulls hard and still reads about right on the gauge. Where should I look in particular? THX

Real boost guage, or the thing that is built in (which takes the reading from the mas and uses it and rpm to compute the "boost" level) ? Cause the Stock guage is unreliable.

yeah, i have an aftermarket gauge. That was money well spent.

Next question.. How would you know you are running pig rich? You have a wideband?

**meanNgreenTSi** · February 2nd, 2006, 06:37 PM

well, it smells like gas all the time, puffs black smoke when i launch, i get crappy gas mileage, etc. You can tell without a wideband...

sounds like 02 sensor problems like i have. if you have access to a data logger id say check both your O2 sensor voltages.

ahh well i have had to use an O2 sensor simulator to stop the check engine light (OBD II crap) could that be doing it?
