Hi Jean,here's a link to your timing belt.

you need scaner

moisture might be getting in the plug wires or coil pack.

CHECK PLUGS AND WIRES ALONG WITH COIL.

I would lean toward the MAF sensor they were known for going bad, which would cause all these codes. It wouldn't hurt to take the IAC off and spray it out with carb cleaner and some WD40, just to cover your bases. Both these units were made by Bosch and the MAF failed alot more often then the IAC.

Usually when your lit up like a christmas tree its a sign of battery not getting full charge. Check the wring harness first, (if alternator is new it should be under warranty so worth checking that out.) Especially if you have a multimeter handy: check DC voltage at the battery. with it running a decent charge would be abour 13.7-14.1. if you're some where around there you're good. if it's below that your alternator is failing in some manor.

It's on the engine, right next to the starter, it has one wire going to it. You don't need to drain the oil. If the light is coming on, you may have bad seals in the oil pan, a fairly common problem, but replacing the switch is a good fisrt step.

Mine had the same problem. You need to get the code from the engine diagnostic. You need to open the two covers near the windshield washer fill and plug the prung into socket A6. with the key turn to pos2 (engine not running) press the black button once, you get a serie of blink as morse code. Mine was a code 3-1-1 witch is a faulty speed sensor (that goes bad when hot but ok when cold). It could also be 3-1-4 or 3-2-4 witch is the cam shaft position sensor. I had the change them both last year. The cam sensor doesn't always log in a fault,as mine did'nt but the car kept stalling, something about being withing the right range but not pulsing.
