Cannot fill gas at a pump

[dinoman]

thanks for that suggestion. Actually attendants usually try pulling the nozzle out, flipping the nozzle upside down, and all other types of tricks that they say work. The gas still doesnt go in without clicking off. I found some wire hangers, so Ill try and see if I can check if there is something blocking the filler neck. I also need to check if that vent line that goes directly back to the filler neck is blocked and is causing the problem.

Since we were talking about ECU-controlled valve earlier, how do I know if the ECU is working properly? I thought the idle problem was fixed, but this morning on my way to work I noticed that the RPM still drops a little too much when I come to a stop. It may be because I disconnected the battery to clear the CEL codes and the ECU still trying to learn the right fuel-air mixture? The purge valve seems to be okay when I took it off and checked it by applying voltage.
