Hey you may look this massage or no but I have a question, I have a 1997 Ford Expedition 4.6L and I saw one of your videos about VCT solenoid but I think my car doesn’t have it so one of the symptoms is that at first I have a knock sensor code and I replaced the know sensor but the thing is that when I come to a stop or a red light, my car start to shake like crazy and the RPMs goes up and down and I already replace the EGR, ICV and still shakes and I want to know if you can help me and tell me to replace the right part, I’ll appreciate your help
