Message: i ran me a wire from the o2 sensor into the truck so that i can hook up my mulitmeter and read what the o2 sensor is saying at wot. at wot it is reading 1.097. to me this seems extremely rich. shouldn't it be around .875? is there anything i can do to lean it out on topend? what should it be reading while just cruising down the road?
