    Hey guys,

    Has anyone else found a cure for this? I have no air pump on my car so that is not the reason for the lean issue. I reach about 14.6 on cold starts but command about a 12:1-12.5:1. What is really bad is a warm start the car goes really lean. It will read about 17:1 on a warm start and buck like crazy, after a few min of running it all clears up though. Just wondering if anyone has found out more. The cold start can be taken care to not be lean, only problem is if it was commanded richer for a warm start, then when running in normal conditions the car would be way rich.

    Mike
