How will getting a code 84 on a ford code reader effect running the next series of test? The book says to fix the first problem before moving . My car does not have an Egr valve.Code 84 is Egr vacuum regulator circuit failure ?
Do you know anything about vs racing 7875? I grabbed one for $750. Put bout 50 miles on it and now it has a ton of shaft play, do you know what causes this? Should I just get a turbo?
