Problem Description and Possible Solution
The variable valve timing camshaft actuators may stick due to dirty engine oil or a faulty control solenoid. A sticking actuator may cause a rough idle and the Check Engine Light to illuminate. Our technicians tell us the engine oil should be checked to make sure it is clean and at the proper level before replacing any parts to correct this concern.

rough idle, horrible gas mileage (8 mpg on a good day), hard start, hesitation at take off, dies when you come to a complete stop and after numerous cranks engine starts again....
Codes for P0014 and P0172 came up after I replaced my alternator and battery. The shop recommends changing the Cam Shaft Accuator and doing an oil change...Not sure if the accurator should be changed or not but will probalby need to follow the mechanics recommendation.
RPMs surge up and down on cold start. Check engine light on. Scanner says camshaft sensor. Timing advanced. Don't remember code number. 4.2 inline 6
The vehicle is idling rough. and its performance is at its all time lowest. The oil gauge will go on 40 then 0 a lot
replaced vvt solenoid code p0014 comes back
Began noticing felt like a slight misfire at road speeds. Nothing outrageous, so thought it may have been bad gas because I had recently filled up. Put some Techtron fuel system cleaner in tank with no change an the service engine light illuminated. Had code read which was P0014 (MAP Sensor) and P0106 (oil crank sensor). Will change the oil first to see if that corrects the issue before taking to my mechanic.
Vehicle threw a code, had it checked by mechanic stated that my Camshaft Actuator was stuck or sticking. Recommended engine replacement.
rough idle, sounds like a 18 wheeler, took it to chevy dealer, and was advised that camshaft actuators does not work long and the dealer stated I need a new motor.
rought idle, check engine light turns off and on about three times then stops for awhile, engine sounds loud when turned on then once in gear it goes away
Check Engine light stayed on. AutoZone checked the code and it was "oil viscosity, Cam Actuator". No real indication of a performance issue.
Went through several oil changes at my usual shop, all with Valvoline High Mileage (extra cost). No change. Read several posts about pulling and cleaning the actuator screens. Before I had a chance to pull the actuator, I won a silent auction for an oil change at the local Firestone shop. Kendall GT-1 Synthetic Blend. Two days later the check engine light went off and hasn't come back on since.
Not making a product endorsement here..just reporting the facts, and suggesting that maybe you r first step should be to switch oils/types and see if that helps.
Was running fine then started to run rough cruise control quit working replaced cam Sensor didn't help but no service light on now flashes when driving goes off if not pushing on gas or going down hill
stuck camshaft actuators because of ignored low temp from stuck thermostat that had recently been replaced
Engine was idling rough for several weeks, then started misfiring on multiple cylinders. Code P0014 on readout. Replaced the solenoid to resolve.
have to keep pressing gas to keep started or until it'll stay started be seld....rpm goes under 1.
Reduce speed light and check engine light comes on and car reduces speed
Check engine light came on. Mechanic diagnosed cam phaser actuator solenoid. $950 to repair…fair?
I hear a Norse when cutting off truck as if the cam is rolling back sending air back into the intake air filter
Rough idle, stalling, and cutting out while driving and idling. When turn ac on makes it twenty times worse.
Service Engine light comes on intermittently. Still an open issue. Plan to pull actuator and clean it.
Rough idling check engine light flashing 4 times then it stops I changed the spark plugs I changed the camshaft solenoid
