sounds like you have multiple problems get a charger on the car .. you might have lost info from ews

Do you think it could be the mobilizer go bust? I do not have the code for it to reset it? Also I have checked all coils and even swap them , only 1 of them was very weak, do you think could be the one for the car miss firing? Do you have any ideas? Pls
