i am trying to buy this car and i was getting it checked out. the guy checking it out said that it was only fireing on 4 cylinders and that the coils for the other 2 were bad. he replaced those and that did not fix the problem. now he wants to take out the MSD that is in there and wire up the stock system to see if that fixes the problem. anyone have some ideas on what this might be. i need to fiure this out asap and anything i could tell this guy that he might not have thought of would help. thanks!
