Just wanted to get somer input. My 04 f150 5.4L threw the infamous P0022 code. I changed the camshaft position sensors and it did nothing, also it's in bank 2 so I swapped the VCT solenoids and reset engine light to try and see if it would switch over with the solenoid but the light came back on 10 mins later scanned it and its still bank 2. Any sugestions to try before having timing chain done?!?!?! HELP!!!
