My experience with P0171 was the car would stall at a red light if I wasn’t paying attention. That and worse gas mileage.Hey folks I think my PCV valve finally failed because I put my finger over the hole and it immediately changed the engines idle. I ordered from Rock Auto a Valve Cover Gasket VS50807R (Fel-Pro) and a 25203036 Valve Cover (GM Genuine).
Is the vehicle OK to drive for the next few days like this? I have to do around a 40 minute round trip from work. I drove it today and it seemed fine but I know the engine was in a lean condition.
I heartily recommend XtremeRevolution’s fix kit. It’s not terribly difficult, just have to make sure you do it right.
