well i have had this code with the CEL on for 2 yrs and it wont die. i have no noticeable issues with performance and mileage is still at 15 by hand calcs. same as the day i drove off the lot with it. not sure what to do, dont want to spend 2k if its not dead yet. when it first came on i went to buy vp44 then the light went off on the way to buy it. i didnt worry and didnt buy it. couple o months later it came on again. this time it has stayed on for over a year and a half. went to go get a pump and light went out again on the way to get pump. still runs fine what gives?anyone else with same exp. ?
