My car has been giving me the DTC codes P0171 and P0174 codes recently. I though it was something to do with the stall issue for the 03's. I've fixed that issue and it popped the codes again. I'm hearing a good vacuum leak from the back of the blower and today I heard it cycle on and off. So I isolated it to the EGR valve. Has anyone had any similar experiences? Thankfully the car still run's fine.
It's bone stock except for the K&N FIPK. I'm positive it's not a vacuum line loose behind the supercharger.
I just read in the service manual that the EGR valve/gasket leak will cause these codes.
I'm just wanting feedback from someone who's experienced this before.
Thanks
