Aftermarket PCV Valve. What do you think?
I changed the PCV valve and the hose connected to it because it was idling rough and added Redline fuel injection cleaner into the gas tank of 95 Int. ES. I just bought the valve from Pepboys. It has been running smoothly until this afternoon. After driving for 1/2 hour, the engine sputtered while waiting at a stoplight. The engine light blinked on for a second and the car seemed as if it was going to kill. After the light changed, it ran rough and at the next stoplight 1/4 mile away, it seemed as if it was going to kill again, but it did not. Up until this incident, it seemed to be running just fine.
Do you think the valve I goot from Pebboys is not good? Should I get another one from dealer?
Any ideas as to what could be going on? Appreciate any ideas!
