random misfire between 2 cylinders
I have an 03 f250... 5.4 motor... I have random misfire between 1 and 3 when engine is in a pull... and only in the upper 2 gears.. (6 speed)... I have had at 2 diff shops and they tell me they have never had this issue... all 8 coil packs have been replaced... all plugs.. and even 2 injectors on cylinder 1 and 3... fuel system has been cleaned... compression is good on all cylinders... these are 20 year exp mechanics.. 1 works at a ford dealership.. they say they are completely stumped.. best suggestion they have is something in the motor is messed up.. wtf.. ok..lol.. I have asked them about cam or crank sensors and they say it would throw a code... I am at a total loss here.. can anyone help out please... thanks
