HELP! On the road and in Trouble!
2004 PSD 6.0. I have been fighting an issue for a long time where the engine feels like it misses when accelerating and when it does this miss, the truck blows a puff of black smoke out of the exhaust.
I checked the EGR system and everything looks good. No dampness under the EGR valve.
Two weeks ago I started getting an EBP sensor error code. I replaced the EBP sensor, and after that everything seemed good. (oh, and I did the blue regulator spring upgrade, and a ccv mod) So this weekend we used the truck to haul our horse about an hour away from home to a show. The truck hauled down fine. Well except that the engine oil did go up to 215 degrees once when pulling up a hill.
Now the issue suddenly came back, and worse than ever. I'm not getting any EBP codes. In fact, I'm not getting much of any codes. Every once in a while I'll get a P0603 code. But the truck is bucking, missing, and puffing like crazy when accelerating. I've noticed that when it happens the EGT gauge goes way up. To like 1300. I'm using a Banks Six-Gun tuner with the Power PDA to get these temp readings.
Here's my working hypothesis. One of the injectors on the drivers side isn't working right. It's not spraying enough fuel into the cylinder to combust completely, then the cylinder pushes the unburned fuel into the exhaust manifold where it ignites, over top of my EGT gauge, and causes the black smoke.
Does this sound likely? Or am I way off?
Is it dangerous to try and nurse this truck an hour home? (there is an International Dealership just down the road here that I could leave it at.)
Is there a way I could test the injectors myself out here?
If I do drive it home, am I going to destroy the catalytic converter? Or anything else?
