David, Close your wallet, no need spending that kind of money. Here are a couple of questions. Are all vacuum lines properly connected ? Has the CO mix ever been adjusted ? Is the tamper proof plug still in place ? Do you hear the frequency valve buzzing while the engine is idling ? BTW both the warm up regulator and frequency valve have an extremely low failure rate, I seriously doubt that either one needs to be replaced.
