C5 2000 codes and won't stay running
We got codes PO171 and PO174 and P1518. We replaced the pcv tubes and valve. Car will start but not stay running. Please help. Did a MAF check and the car still cut off even faster then before. Pls help.

Sounds like a BIG vacuum leak to me. Not familiar with the P1518. Maybe the throttle body is bad or blocked from closing all the way. Have you cleaned it?
