2004 zx3 2.3 liter engine. 1 week old from the dealer, check engine light is very dimly lit , even when key is out of ignition. Does anyone know what this problem is? The carfax came back ok...
That one I havent heard of before. Normally a flickering CEL would indicate a misfire, but one that stays dimly light even with the key out would tell me that somehow that bulb is still getting power, like a high resistance short.
First things first, be sure there are no codes set just to make sure there isnt a reason for the light to be on in the first place. You can take it to Autozone and they can read it for you. Ford is going to the newer CAN protocol so if your car is using that protocol Im not sure Autozone will be able to read it. However, if it still uses the ODB II protocol then they will be able to.
If they find no codes or pending codes (be sure to check for both) then I would start looking at the electrical wiring. I wish I could be more specific but that is all I can think of at the moment.

It whines a lot, but I like it
most likely the connector on the back of the cluster is loose. seems a few people on other sites have had the problem and it turned out to be this.
disconnect and reconnect it and see if it helps.
one other cause is bad engine grounds. loosen and retighten all the ones you can find in the engine compartment
