well my SSS has been feeling really weak. always had a werid idle.. but never threw a code. would knock on 87(when gas was expsensive, only would get on it when needed and not full throttle, and there suppose to be on 93 anyway). but just felt weak. so my cousin and i checked the fuel pressure at idle and reving it up and in drive with a load it would sit at 62lbs.

we hooked the tech 2 up to it and saw it had 124 counts of misfire on cylinder one , and 36 on cylinder 3. then we checked the coil to see how strong they are and see if one wasnt shooting as long of spark. both cylinder checked out fine. which leads me to wires as plugs are new. but we decided to check cylinder 5 and when i started truck up it made this knocking noise like a rod. but then went away. oil pressure fine and has plenty of oil. we start it again and my cousin gets under truck and puts a screwdriver on the cat to listen. and its rattling horribly.

so we narrowed it down to cat making knock sensor go off and pull timing. and im ordering some taylor wires and gonna check all the plugs.

ive been hearing a slight rattle but anyone have any idea why the noise got extremely loud after checking the coils. do you check maybe well it was idleing with a cylinder down fuel got in there and broke it apart maybe?
