I cant figure out my rough running gtp. I have a lean in bank 1 code 0171 i believe, i put new plugs and wires on, new mas air. , checked for vac leaks and im having no luck, I have 2.5 headers, with 3" all the way back running 3.25"pulley anyways im stuck on this Any ideas for me that be great. thanks
 


Do you have a code reader than can do live data or a scangauge that can?

Check to see what your long term fuel trims and MAP in vacuum is reading.

Sounds like it still has a huge exhaust leak or somthing internal is wrong.
