Loud timing or cam sensors
I have serious bad idle and huge noise after warm up on my 4.6 2005 mus. gt. I think the sensor or electric plug or cam is bad. it runs fine most of the time. after driving and at idle it starts rattling loud and wants to stall. if i hold idle up, it clears up, if i let idle it gets bad again. has not done it on hiway, only street light to street light. please help. thank-you. also has 160k miles. Do i have to pull the heads to change the sensors?
