it all started when I was towing a travel trailer and came to a stop, my engine would make a really loud knocking sound and almost die. almost like losing gas pressure. so I took it in and they told me it was the timing chain. so spent $2500 on new kit but when I got to camping with the trailer again it did it again. I was very upset and took it back they opened it up again and looked and said it was all good. again it happened. so I just started throwing parts at it hoping one would work. thought well it acts like it is loosing gas pressure so I thought maybe fuel filter and reading about that it said change fuel filter and FPDM at same time and looking on utube I saw a lot of FPDM corroding because of hard winters. and on RockAuto it was under 2007 so when I got the filter I got the FPDM with it and while on lift I looked everywhere. good to know Im not blind. so then I thought will maybe its a timing issue so chain is new so I thought spark plug so I went ahead and changed them (which I have learned I will never do that again) along with coils and boots. it still does it. so now I have read to change oil thickness so next im going to change from 5w-20 to something thicker to see if it goes away. it doesnt do it every time I stop, just does it a lot when I pull a trailer. and after I rev up engine it goes away. never a check engine light or code. trailer is only around 7500 so I know I am under wight limit.Are you having problems with the circuit
