yeah its like a lean code, usually related to the MAF. I would get maf cleaner and clean the maf. I think theres a how to on here. and see what happens. Specially if you have a 03 and have never cleaned it, I bet its dirty as all get out.
so far, so good. did it today. electric plug was a little difficult to disconectt so when i got it apart i gave it a spray also. thanks to genvibe forum and all you guys. you,ll save me alot of $$ and fewer headaches.
