i have on an advanced scanner codes p0008 and p0017 and p0017 and they reappear after clearing them out . the car picks up well on a cick down up till a certain high rpm when you experience a cut off in power which gets resumed once you ease the accelerator pedal a little . further we have had to change some injectors on the cts
2008 three times now while they get faulty and white smoke appesrs from the exhaust
and we find that these faulty injectors are wide open for excess fuel into the manifold . further upon starting the cold engine
you hear for seconds a backfire sound which goes later
JA: Where exactly do you think the noise is coming from? And how long has this been going on?
Customer: for few thouand miles regarding the cick down problem but the injectors problem goes away when we change them . mechanic says timing chains
and gears and tensioners have to be changed to fix the problem . i do not know if it is a proper diagnosis
JA: What is the model/year of your Cadillac?
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: no a mechanic
JA: Anything else you want the mechanic to know before I connect you?
Customer: could the problem be simpler than what the mechanic claims
