engine knock

[AStewart]

I have an early 05 with 9K and no mods. For the last 500 miles it sounds like a gasser with a bad timing spark knock. It rattles mostly at slower acceleration. I can't hear it at half or full thottle.

Help

In colder weather mine does the same thing...



Of course the dealers say "it's normal"

I will throw my $. 02 in here... try SEA FOAM fuel conditioner... . my truck had that damn knock also and so I tried this stuff (avail at NAPA) and it works (My thought is that you have dirty injectors from some poopy fuel)... I poured 2 cans in the tank (full) and changed my fuel filter and added one more can in the filter canister... . noticed a measureable amount less noise in about ten miles... try it... cant hurt
