My fathers 09 GT with 37k miles (always kept up with maintenance) is throwing codes and runs/sounds like its only running on 6 or 7 cylinders. I haven't turned up much on google but sounds like a possible Variable Timing Solenoid failure on the drivers side. Hes got the hotrod cams in it so it runs rough anyway as it is kinda hard to diagnose the noises and idle.

Anyways is there any sure way to tell if its the solenoid or the phasers before taking off the valve coves? Feel free to post your .02 cents

When were the cams installed? Did these problems begin right after?

Bought new Variable Timing Solenoid from ford dealer, changed out drive side one and it fixed the problem.
