My CEL went on early this week and i had some definite lag in power. I went to Autozone and had them scan my car with the OBDII scanner and the problem came up "too lean bank one." The guys at Autozone said that i probably had a vacuum leak. I checked all my vacuum hoses with a stethoscope and didn't hear any hissing at all and every connection was solid. Has anyone ever had this problem before? Any suggestions? Want to hear what you guys think before i bring the car in. Oh, what does "bank one" mean?
if you have any kind of Intake and you put it on yourself you crossed a couple of the vacuum lines. you may not have a leak but something is crossed. This happened to be when i put my new clutch in, the dealer put all my stuff back on the wrong way and the next day the cel came on so i took it to a hole in the wall shop and they fixed it right up. if you don't have an Intake then i dont know what to tell you. just dont take it to a dealer or they will rape you.
