How are you powering it? Simply because it clicks doesn't mean it's functioning. Take it off and make sure it opens when you power it. Blow through it or shoot some compressed air or carb cleaner through it. After all, it's just a solenoid valve. While you have it off be sure the lines to it are clear also. And look for rust in the fittings. Why replace a relay when you can easily test it? Power it and measure the contacts. Or put it in and out of it's socket and see if your freq valve clicks when you do that. In fact, it should buzz at a fixed cycle. (The lambda relay should click also, assuming you have the rpm relay jumpered.) If not you need to see if there is an output at the freq valve connector. Be sure to check both pins agaist each other, the ECU supplies a ground so there will always be + 12 vdc at the valve's connector if you reference it to the engine block. If not, your wiring or power to the ECU would be the next thing to check. If all that checks out your ECU is hosed. (I doubt it though.) Yahoo!
