There is a Shuddering knock and ticking noise from the engine theres 57,000 miles on the engine everything is stock and i jsut bought it 2 weeks ago ive been told that im down a cyl and wanted to know what could be wrong
ive changed-Spark plugs,Fuel filter,intake filter,oil&filter

 

Change plug wires, and run injector cleaner.

Is the knock just a sound, or can you actually feel it?

 

its not the wires i checked all cyl are firing. and ran fuel injector throught im thining its injectors them selves or the valves

 

if it is at idol or does the knock get louder with accelration.? could be fpr

 

If all the cylinders are getting proper fuel and spark, and you are sure one cylinder is not firing (dead), then that cylinder probably suffered mechanical problems. Do a compression check & see if a bad cylinder shows up. The noise could be a problem with the valve gear, which could also result in a dead cylinder.

 

hey could a dead cylinder feel like a little skip every now and again??
