did not know what to do with my vectra when it went in to limp mode. changed the coilpack sparkplugs and all that still would not fire number one spark and it was very jumpy in neutral.then someone said it must be the ecu so found a website called ecutesting.com where they repaired it and sent it back the next day by royalmail recorded delivery. put it on the car and now its running like a 1.8 16v sxi should zoom cost around 300.00 pounds inc p&p and vat. ecutesting.com where thay do uther things aswell is a real good anser to all ecu problems.
