I have a 2010 Ford F-150 (100,000mi). About 3 times over the past 6 months, if I was backing up a trailer, it seemed as if my RPMs dropped in idle and the motor would run rough. Afterwards the light would disappear and the truck ran fine. Yesterday my [engine](/topics-engine-ford/) light appeared. I pulled the codes; P0012 and P0022). Do they typically replace the phasers or should I try something else prior? Mechanic's Assistant: Is the rough idle intermittent or consistent? I’d say intermittent. Example - only when backing a trailer. Or, yesterday, backed down driveway, felt it slightly then noticed the light. Once I put it in drive it drove as usual Mechanic's Assistant: Are you fixing your F-150 yourself? What have you tried so far? I’m planning on first changing the oil - Mobil 1 High [mileage](/topics-mileage-ford/) and get a filter from Napa. I’m primarily curious what are the odds it’s something seriously significant Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? No ma’am. I’m simply concerned because money is tight and people keep telling me “horror stories” abt the problem

HI Was afraid of that. Unfortunately you are looking at timing chain kit and phasers. And I would have the oil pressure checked first. Must have a minimum of 25 PSI on a fully warmed up engine. If under that, then an [oil pump](/topics-oil-pump-ford/) as well Anything short of that is a waste of money and time on this engine Thanks for using Just Answer and letting me help you. I hope I provided what you needed. If you find more help is still needed, let me know by listing out any remaining questions you have on this concern. I hope the remainder of your day is well.
