That's what I did pouring it down the vacuum line into the purge solenoid. I am trying to find out what to change near the gas tank but I cannot find anything that resembles the purge selenoid - I did find a set that I think is the purge canistor but where is the selenoid on this truck for the tank? When I pulled the electrical connector off the valve the vacuum went away.
I have been doing some research. But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off. However, the system was troublesome, misunderstood by customers, and a rash of unpredictable failures led to the technology being quickly retired. The volatility of gasoline has both its pros and cons. This is especially true right after you fuel up the vehicle. I have checked all rubber lines and they are all 100% intact as I have replaced them all.
How to Fix The most common fix for this code is to replace the purge solenoid valve. If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one. Alina- Evaporative emissions are basically gasoline fumes. Caution: Do not blow out purge lines or vacuum lines with shop air unless you are sure they are completely disconnected. Remember that the more often you rotate your tyres, the more evenly they'll wear, and when you have the tyres rotated, you should also get them checked for balance and alignment. If your spark plugs look good, problems with your ignition system can also preventing a spark. Richard- Please give us some vehicle information to help you out.

Refueling would be difficult as well, because air in the tank would have a difficult time escaping at the same time as new gas is being introduced via the fuel filler tube. The lean fuel mix error may be accompanied by rough idling, engine misfires, hesitation during acceleration and overall poor engine performance. Eric- I understand your concern. Also, make sure you are using a good factory gas cap. My truck is has major leaking gas from canister. If the purge valve checks out good, either the problem with the valve is intermittent or there is a problem with the fuel tank pressure sensor.
On the other hand, since gasoline boils as low as 95 F, and evaporates at even lower temperatures, basically until it freezes, at some -50 F, depending on the exact blend.

You should also check that the spark plug gap is set properly. To test the fuel tank pressure sensor you will need to have a high end scan tool to monitor the tank pressure with the gas cap removed.
