So, I have not been so quick to respond to the check engine light and ding. I've found that not reacting to it means the less often it will go off. After taking it to the dealer to have a warranty issue taken care of, they gave me a list of other things that need to be fixed. I'm just not sure what I can do in a day or afternoon versus taking it to a shop to ensure the proper coding for the changes. Here is the list:

- New plugs. If I do this will I need to adjust or reset anything and do I need to replace the ignition coil and cables?

- DISA Valve. They say the mixture is off and after running the "smoke" test, they found a leak around the valve. Is it simple to replace and will it throw a code?

- Windshield washer pump weep hole leaks. I've seen a few DIYs so I'm confident I can do this. Has anyone ever had this happen?

- Micro Power Module. Shorted out. Surprisingly, according to the dealer, she is still running. Will this throw a code if I replace? Any suggestions on a better location for this so it doesn't flood?

Any suggestions and ideas are greatly appreciated. I'm obviously not a mechanic, but I can follow instructions and have done other repairs on her and other cars. Thanks for the help.
