Celica Forums General Discussion Exterior Celica running too lean

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?

'bank one' means that it will cost you a lot of bank to fix

i'm kidding of course... i'm sorry to hear about it man, please keep us updated. do you have any mods, or have you done anything to your car btw?

I may have had the same problem...but I fixed if before I had it checked out...my CAI had slipped off at the top end

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.
