Hello,
I have found surprisingly little info on issues with the vCT for 2011+ 5.0L mustangs so I thought I may ask here. I have a 2012 mustang gt with about 115K since new. There is a BAMA street tune and intake for the past 100K miles. Just recently when accelerating hard at 4K when the VCT is normally engaging it feels like its half engaging and I have less power then before. I did a few pulls to confirm it was pretty consistent in every gear and parked the car. My concern is eating the timing chain and everything going boom.
Based on the info I was able to find first step seems to be to change the oil as older oil may gunk it up and cause this so thats on for Saturday. I checked the oil recently and it was fine and I always do it myself. It was done about 6K miles ago which is longer then I typically wait. The only other thing I can think of is the actuator solenoids for the VVT system. I have ordered 4 from CJ pony parts (nobody stocks them) that fingers crossed I will get on Saturday. If the oil change doesn't work then I will change those.
So few questions.
Is my logic here sound? am I missing anything? My understanding is there is no fuel filter and the car is fine unless the vvt tries to engage.
How obnoxious will changing the sensors be? I understand I need to remove the valve covers? anything unusual to watch for or any youtube videos to help? I have always worked on cars and am an engineer for a Ford supplier so I know I can handle it, but you never know what kinda crazy it may turn into.
Thanks for any help.
