I would start by looking at the status of the codes. The only codes showing current are P0102, P0412, P0418, and P0443.
Are you having driveablility issues?

??? They are all "old" Can't believe they didn't reset the codes when they had it. You really need to have it reset and start from scratch. Almost all say they set of the SES.

Sam.... did you ever get all of this resolved??? In another thread before this SES issue you had the Mortor Mount and some other parts replaced and mentioned a gas milage issue.....
All of that leads to issues I have been experiencing for oh about 13 months... I am too lazy to pay 1000 for the 3 o2 sensors and the exhaust, but when my cat went, the o2 sensors followed, and the Maf was next.....
try taking the Maf out and spraying it with some cleaner and putting it back in, also look for a vacuum leak... if your CEL isnt on and the cat isnt coding, then the fuel milage is an intake issue(maf), or a leak in the exhuast or vacuum.... normally the fuel lean codes will set off the CEL though if it was any of those problems......
let us know if the dealership ever figured it out...most dealers dont know sqat about the northstars.....
