Pontiac Problems? Ask a Mechanic for Answers ASAP
HI, my name is ***** ***** I'll do my best to help. Please stand by momentarily so I can look up your vehicle's emission application. I'll be right back with you.
Ok, thank you for patiently waiting. The most likely cause of this code / issue you are having is a sticking Evaporative Emissions Purge Solenoid Valve (EVAP purge valve). This code is generally associated with the purge valve when it malfunctions or sticks internally. I have had the pleasure of fixing this type of issue with this code many many times. Almost all the times I can recall, the purge valve was the culprit. This will also cause excess fuel consumption (poor mileage) and also a hard start condition as it's actually a vacuum leak to the engine when the valve sticks. As for the jerking you experienced on acceleration, that may be another issue all together.
I hope this is helpful information. Is there anything else I can assist you with? If so, simply let me know. If not, thank you so much for using just answer!! I'd greatly appreciate a five star rating as well. Thanks again!!
