95 psd very rough idle

So this morning I let my truck idle for about 20 min to warm up then I drive about 100ft then it starts running very rough like its out of fuel, or like its not running on all cylinders and the check engine light comes on. Also it's not throwing any codes except for exhaust back pressure sensor. I was thinking injectors maybe but I'm not sure. What do you guys think? Help is greatly appreciated. Thanks

Unplug the EBPV connector and try again. It's the one right about where the fuel pump is in the valley. It'll be under the right side of the turbo (as you are looking at it but on top of the pedestal). Small 2 wire connector.

I unplugged the ebpv and did nothing. Then bought a new fuel filter cause it looked dirty, once again didn't help. It revs up but with no power. It sounds like one cylinder isn't firing. Checked the four plugs on the valve covers and none were burnt but three of them had oil on them. Injectors maybe??

That where I'm headed too. The insides of the VC gaskets should be dry. With the engine idling disconnect each of the four VC harness connectors and listen to the motor. A change in idle says that those two injectors are not likely the problem. Move to the next and you are looking for a no change in idle with the plug removed. That means the two injectors that you just disconnected weren't firing anyway.

Time to open the VC up and look inside. Your local NAPA will have the Under Valve Cover Harness and the VC gaskets. You can run the motor with the VC off to see the injector action. On the tops of the injectors is a oil dump port. When the injector fires it'll release the stored oil back into the rocker area. Not really messy. Look for the injector that's not spitting oil.

How do I replace the plugs on the inside? Or is that apart of the gasket?

OOoooh attached thumbnail, my might foe, we meet again....


At the same time don't pinch pennies and make sure the kit includes, or that you buy separately, the pigtails for the first several inches of the outside wiring harness. Solder your connections don't crimp them.
