i was having a missing problem and determined it was the ecm so i replaced it and the car ran fine for a day . next day i got in the car and it felt like the tranny was slipping really bad . i checked the codes and i am getting e75 (vss) . this seems like to big of a coincidence for this to be happining all of a sudden after i changed the ecm , i am going to get another ecm to make sure this new 1 is not bad also . if it still does it and i need to replace the vcc does any1 know where it is ?

sheesh , got a new ecm and now its running fine again . i hope that is the end of this because if it starts again i guess that means somthing is frying these ecms .
