More problems, help!

I had already done everything you mentioned. I disconectted the negative battery cable for a few minutes figuring that would clear the memory. I drove around in stop and go traffic several times. I raced the engine a little bit hoping that that would "settle it down", but no go. In the morning I have to hook it up to get it to turn over. Then I pull it out just enough so that there is no connection. The Check Engine light comes on, but the idle drops to 1,000. Could the fact that we are having a cold snap here have any bearing on this? It's been dipping into the upper 20's to low 30's overnight. Anyway, I have this really good "Ultra Copper" gasket maker and I used it to put the old one back together. This weekend I will swap it out and see what happens. If I can't resolve this issue, can I go to my own mechanic, or do I have to go to a Toyota dealer? I'm not used to cars with computers and diagnostic codes and such. Would my mechanic, who I trust and is very reasonable, (I found him by word of mouth) be able to hook this car up and find out what's wrong?

Thanks,
