I have a mis fires in almost every cyclinder but not at the same time. I have a excessive flow in the egr and my truck just started clicking in the engine i dont know wtf to do anymore. check out what i have Already done...

Replaced egr,dpfe,coils,spark plugs,fuel regulator,fuel filter,iac,air filter....
Cleaned the fuel injection,spark plugs , plug wires, air intake, egr intake, throttle body, hoses....

Still the same problem. good idle, bad shaking and misfiring when i hit the gas....

can anyone help pleas......

 

How do you know its misfiring in every cylinder?

Also, how will cleaning the plug wires help any, I suppose to mean you cleaned the contacts? I would go ahead and replace the wires since nothing else has helped.

 

My 4.9 was doing somthing simular I found a problem with the seal between the throttle body and manifold... start looking for a vacume leak.. could be the issue..

Is the timing good?

My issues are 100% solved yet but that leak on the TB was a major part of them.
