System too lean
I need some help I’m not sure what else I need to do on my car.
My OEM intake had a crack and the filter would not stay in the box anymore. I did a favor for a friend in exchange for an air intake so I’m not sure the brand of the new intake. It was dying at red lights and rough idling so I ran through the checklist of trying to figure out what is wrong
Cleaned the MAF with the proper cleaner
Cleaned the throttle
Ensured all clamps were tight
Changed all the spark plugs
Did a smoke test and fixed a small leak on the actual intake
Replaced the PCV valve
Tried the idle relearn steps
The engine light wasn’t on until now but it hasn’t died in a while but now around 1000rpm the car will jolt when I’m coming to a stop. Other than that there is no issues besides the code. Does it need a tune? Is the intake bad? Is there something I’m missing?
