im on my way to my uncles house. I pull out of the naighborhood revved first out to 4k just trying to get out there quick cuz of oncoming cars. Then i notice the check engine light. i let my sis hold the wheel while i pull out the scanner. i pull the coad and its lean in cylender bank one. so i swapped plugs from 1st cyl to 2nd cyl to see if it was a plug probblem and it threw the coad again in cylender one. So idk what it could be. Ajss is giving me a 3.3 until i can get this figured out. Thanks. Mods are in sig.

 

Ok, if it says its lean then your spark isn't the prob. It's most likely your #1 injector...so it could be faulty and have died, or it is clogged.

 

tere brand new 42s from zzp

 

well maybe check the wiring harness to make sure they are still connected properly

 

gm tune + 2.9" could = lean fuel trim. Or if you have an aftermarket intake

 

Bank one is not cylinder one. They use bank one and bank two to show codes like that since we have an inline motor we only have one bank so they call it bank one. It is just a lean code... do you have a wideband??

 

No i dont have a wideband. the coad is p1071

i have a airbox mod

 

remember just because it is new doesnt mean its good. could be faulty. pull the fuel rail and injectors clean them out. its an easy job

 

i figured it out it was a massive vaccume leak

 

Wow way to go, so when are we doing my headlights and wheels

 

never
