Okay, trying to fix things I been meaning to fix. I want to find out whats causing powerloss/bad gas mileage. I havent ruled out the cats yet, I'll have my exhaust tested to see if there's any restriction. In the mean time, If I log some data with the auto tap of my car, can any1 take a look at it for me? and what data would be needed? while car is idling? crusing? I know its kinda of a broad thing to cover, just not sure to narrow it down any further.
