Hey guys well I just bought my truck a couple months back from a person who sold the truck to me with a misfire.I thought it would be an easy fix but I cant get it to stop misfiring. It seems like one cyl is not firing right but I cant pin point it. Things I replaced so far are ngk plugs and plug wires, cap, rotor, fuel filter and also drained out the gas and put shell 91 hoping it would be bad fuel. Im kind of out of options now and dont know what I should check out next. Any help would be much appreciated.

 

Have you tried unpluggingconnections on each fuel injector to see if one doesn't make a difference?

 

No to be honest with you I haven't done that yet. Ill go ahead and try that tomorrow and report back. Thank you...
