Im getting this weird noise kinda sound like pressurized air and I got some lean code p0171 and p0174 which I can guess the noise is the cause. However I can’t seem to pin point exactly where it would most likely come from.
I don’t have a smoke machine to test it and I’m a few hours away from a good shop.
Any ideas?
