2010 Tacoma 4.0 Rough idle - Codes P0018 , P0021

Can anyone help a new member find problem. Thanks

 

Those are timing codes, first step is to check your engine oil level and condition.

 

Thanks for your response and helpful videos. I am not too tech savvy with computer or forums. Any advice is much appreciated. I changed oil and filter less than 1000 km. ago. Oil still looks like new and level has not changed. I used better quality oil and filter. Truck has recently developed a pause upon acceleration from a stop and then it lurches . This is separate from rough idle which seems to occur after vehicle is warm. It has occurred multiple times towing a small load and also at times without additional load. Vehicle comes close to stalling at very rough idle but improves once underway. Where should I be focusing ? Thanks.

 

You may have a Bank 2 VVT Oil Control Valve sticking then, quite a bit of discussion about it in the thread below although they had a problem with Bank 1 the concept is the same.
The low/rough idle could be a result of the timing being off or your throttle body may be dirty causing a low idle.

Thanks for your advice on my problem. I did the following as you suggested. 1) changed oil and filter 2) installed new VVT oil control valve 3) cleaned MAF sensor 4) cleaned throttle body. Result: No hesitation or rough idle while towing or not. Just better performance. Thank you.
I have since changed out my front CV axles and am installing new front brake rotors , calipers and pads. I have cleaned hub and wheel surfaces but have excessive ( .023") lateral runout on passenger rotor. Drivers side is (.002") Do you think I need to change this wheel hub and bearing assembly ?
