Hello all,

I've been having a check engine light on. *It says engine running to lean on bank 1 and 2. I replaced all 4 oxygen sensors reset the computer and drove it 50 miles and then the same code came up again. I've reset it twice now and it keeps coming up. I've checked the battery and the vacuum system for leaks and sprayed the carb with lots of carb cleaner. Just last night I sprayed the mass air flow sensor with MAF sensor cleaner. Other people have told me it's probably the vacuum hose behind the supercharger. Does that sound about right? Any other ideas?

Any help or advice would be greatly appreciated!

Thanks in advance,
Brandon
 
Mine was the same. The vacume line going into blower was shot, fixed it all up with a change of a 2 dollar hose.
