check engine light on 03 supercharged toco

[superchargedtoco]

Ever since i supercharged my 03 toco the check engine light has come on and the technitions at the toyota dealer cant figure it out! the code that comes up just says its running lean and thats all we know. It seems to run good but lean. Whats the deal. Never had any problems till i had the supercharger installed. Please help.

So The tech called and apparently the throttle body gasaket was not mantled correctly and was pulling in extra air which expaines the lean mix and therefor triggering the check engine light. I hope it stayes off. Intake, Magnaflow exhaust and now the trd supercharger! 280bhp? Feels like it!!!

If you continue to run lean, you may have to do some fuel mods.

There is some information in pingfix on your engine. The others are generic supercharger problems you probably should look out for.
