2004 f350 6.0

[Michael Fernandez]

Cruising along on interstate 70-75 mpg, got off exit to home, and engine started running rough, pulled two codes P0271 and P0272 both for cyl #4, pulled ficm and sent to bulletproof for testing, results ficm is good on power side and logic side also.

going to check harness at connection to injector plug.

Is there any way to buzz test injector old school "turn key key push button etc...."

Hi Michael-
Can you provide some more details about your rig? Curious about miles, modifications, and what have you tried...
With these fords, swapping injectors is probably not worth the work unless it is a replacement.

Think checking the harness is a great place to start, with at little dieE grease on connectors.

Good Luck,
