A while back our Sonata started doing this thing where it'll start jerking when you accelerate and sometimes the CEL will start flashing and it'll go into limp mode. The code that it throws is P1326. I've replaced the knock sensor already and that didn't seem to fix anything. I've also replaced the cam follower located under the high pressure fuel pump on top of the motor which didn't help either. It only does it every once in a while. It also makes a little rattle noise coming from the engine bay when the engine is under a load (going up a hill at lower RMP's).
Any ideas what this could be?
Any help is appreciated.
