If someone took a **** in your intake that could do it.

Re: (JDM_teh_WIN!!)

Too rich can be caused by a clogged air filter or sticky/shitty injectors or a hole in the FPR diaphragm. Too lean can be caused by vacuum leaks or a weak fuel pump, for a couple examples.

Re: (JDM_teh_WIN!!)

Did you add a FPR, changed your injectors, O2 took a ****, changed your ECU to some custom ebay chip? What's the setup?

Re: (camarine2003)

Do a full tune up, and clean the injectors an change the air filter(just in case), an make sure the 02 sensor isn't bad....if that doesnt solve the problem could be something major
