Here's the latest .... We went to the dealer and was told part #12655421 was wrong that the correct part was #12646784 :/ blah!!!!!!! They told me to bring my car in and they can take care of it BUT I need my arms and legs (which is what they'll charge) so no can do ... I'm really on a mission now!!

 

seems the dealer is using the old numbers yet.

This is from a post by Whopper listing the numbers oldest to newest
Intake 12628347 = 12646783 = 12655420
Exhaust 12628348 = 12646784 = 12655421

 

Thank you for the clarification!! Funny how I trust this site and it's members more than the dealer!! Thanks for the info ... I will post the outcome after my car is worked on!!

 

**UPDATE** it's been 2 weeks since the part was changed ... (Cost $54.06 and it took a whole 30 mins) the lights are gone, no hard shifting and my baby is running smooth!! Thank you all couldn't have done it with out you lol specially the step by step instructions from whopper!!!!

 

EXCELLENT NEWS !!!!!! Love them happy endings.

 

me too!!!!!!

 

Cool!!!! Glad it worked out for you. 30 minutes? Almost a record!!

 

Just an update ... No problem with the fix mentioned above!! I think I was traumatized and sometimes "feel" like it kind of slips a little BUT just as soon as I feel it .. It goes away :) unless anyone knows of related problems to the abode mentioned code ahhhh!! Ok I'm freaking myself out lol thanks to all who helped

 

Mine has started to do the same thing.....
