Hello,

For a week my 04 coupe w/52k had been stalling after 10-15 minutes of driving. It would crank, but not restart. After an hour of cooling down, it would start with CEL, but would only run another 5 minutes until it died again. Code was first P0410, secondary air injection system, then a few days later P0335, for CPS.

I got a Duralast CPS from Autozone. The harness plug doesn't click into position like the stock one did; it in is position, but takes little effort to pull off. I bought a K&N recharge kit and soaked the filters pretty well and followed the provided instructions. Bought used; it came with some blue Septre cone air filters.

After install, started right up with no CEL; cleared the ESP light with wheel rotation. It ran idling for a good ten minutes, but as soon as I was in gear and tried to accelerate, it got a CEL and died. I tried this a few times with the same outcome.

I bought an Autel MS310 scan tool. The freeze frame says:

DTC freeze frame - P0335
Fuel system 1 - CL
Fuel system 2 - CL
Load value (%) - 31.4
Engine coolant temp - 187

Short term fuel trim 1 (%) - 6.3
Long term fuel trim 1 (%) - 0.0
Short term fuel trim 2 (%) - 6.3
Long term fuel trim 2 (%) - 0.0

Intake manifold absolute pressure - 12.1
Engine RPM - 2150
Vehicle speed MPH - 11

This is a great site and I have benefited from it for two years. Thanks for all of your support to the community!
