Could my indie take care of a fuel/air mixture problem or is it a part I would need (such as throttle body or???)?
If you have a DMM that can measure duty cycle you can do it yourself using the diagnostic port and adjust the lambda/AFR. You can also test the O2 sensor with the DMM, do a search for "lambda" and "duty cycle" within the tech section here, there are some great guides. The DIY links also has a couple crash-course type documents that are a good primer. Wish I could help more but I'm still learning this as well...
