Rajaie: spark plugs changed week ago, car shakes this morning 54F!

Before I go with the vanos kit, I tried to replace all my spark plugs a week ago. The cold shaking seemed to be fixed... for a day or 2.

This week:
- every morning, the engine shakes and brings up the engine light. It does not stall though... restart the car will make the engine light go off. The temprature was 54F this morning, not so cold, but the car still shook...
- 2000-2500rpm engine makes some noise that does not sound good, and car is sloppy. Can't make clean pass when I needed to.

Then I went to AutoZone to read the code, the guy used his OBD II but got no code, it says 'passed'. wth? I ask him if he can check all codes that are stored, he said there are no codes stored. wth??? I don't know what to say, just hoped i knew how to use that mf.

- replacing 6 spark plugs did not make the morning shake go away!!!!!
- Can you please let me know if there are codes that I can retrieve???
- I will order the vanos kit and repair vanos this weekend, by myself

Do you think this is 90% vanos problem? or I still need the codes retrieved before making any decisions??????

Thanks a lot!!
