Good morning everybody, I just had a question. I am planning to scan my car and I was wondering what would I look for in terms of running rich? And is there anything else I should check for when I scan my car? Any ideas and suggestions would be greatly apprecaited. Oh yeah it would help if I tell you what scan program I am using, I am using Diacom. Thanks.

 

I have an online guide to Scanner Data . Shows what typical readings are, gives some background on how the fuel control system works, explains short term and long term fuel corrections, etc.
