  1. Can you drill that SOB out? I think the bolt head just holds it to the knuckel, correct? I bought all new hub bolts for when mine are getting replaced.
  2. after further research it may appears the injectors are acting up. I found a good replacement that people are swearing by. The replacement job is somewhat involved. But not awful. Since the intake plenum has to come off, I may look to do the FPR anyway. Looks like a weekend jobby but not too bad. https://www.summitracing.com/parts/URM-6016
  3. Curiosity got the better of me. I took a closer look. The portion of the small bypass hose where it connects to the threaded adapter to go into the top of the water pump, appears to have a very small leak. I loosened the hose clamp, repositioned, and re tightened. Appears to be still leaking (but even less now, no belt squeal). I have ordered the bypass hose, new upper and lower rad hoses as well. I think I'll just swap them all out now (it's winter here). Or I may just swap out the bypass hose for now as the rad hoses don't appear to be in awful condition. I'll tackled the water pump (and upper and lower and lower rad hoses) when the weather is warmer and I can do it outside. I'll hold on to the water pump of course. Thanks for the info again, it is greatly appreciated! I think shocks are on deck next, just gotta order them. Should be pretty easy to swap. I've started soaking the bolts down with liquid torch/weasle piss.
  4. Hey guys. Thanks again for all the input as I work this 2000 (7.4L) k3500 back to good shape. It has been making me money plowing, quite a bit this year. I have the front rotors/hubs/wheel studs all ready to go, just need to get the job done. Seems I have a random issue showing up now. Truck will seem doggy, horrid MPGs, can almost feel it missing damn near but will idle fine. When I get it going it will hesitate a bit up until cruising speeds. This is intermitent. Yesterday it ran flawless and had great mpgs. No flashing CEL lights, so it can't be an actual missfire. Gotta believe the ignition is good. So I'm really thinking fuel. I have not yet hooked up my live monitoring when it does this. But plan to do so. Was thinking intake manifold, but if that was the issue I'd have it all the time (right??). I do have a code for an 02 sensor but that's because I believe I have 2 that are deleted. Truck has a new ECU as well FYI. I'm wondering if this is fuel related though. Possibly the fuel pressure regulator going bad. I have no way of proving this at this point, but it's on my radar. Have also checked into the MAP sensor, but if that was bad, I'd have a code. This "issue" will come and go. Sometimes it runs great, and randomly it will do this. Normally I can shut the truck off and restart it and most of the time it goes away, but not always. It was really apparent when I was pulling my enclosed trailer this weekend with 2 4 wheelers. No engine temp issues. Transmission shifting great. RPMS seem to build ok, but it will hold them a little longer. No codes yet.
  5. Got the part and verified it appears to be the right one. Has 1 outlet on top which mine does too. Pulley location is threaded too, which is good. I will just have to find time to do this. Going to replace the upper and lower radiator hoses and the bypass hose too. Might as well. Already has a new t-stat. Might flush the block too, we'll see. Thanks for the info everyone!
  6. I did not mention that, lol. And yes, fully programmed with my vin. I had to do the security bypass. Flashmasters.com If you recall from my other thread, they stated the ECU was bad, when it was in fact the speed sensor tab that was bent. Glad that fiasco is over. Sent from my iPhone using Tapatalk
  7. Truck has a new ECU now so maybe that’s why it’s throwing the code because it only has 2 Of the 4 sensors. I think they sell dummy plugs to trick the ECU. Sent from my iPhone using Tapatalk
  8. I order all my AC Delco parts from amazon truth be told, they have the best prices pretty much every time. I will unplug my new sensor and check my readouts on my bluetooth scanner (realtime). But the code says B1S1, which would be drivers side. The one replaced was the passenger side as that was the code last time.
  9. The truck is older (2000) so ill probably opt to just replace the other sensor. That way they are both new. Parts site (ac delco) show 2 upstream and 2 downstream. Hilarious as I only have 2 total. Sent from my iPhone using Tapatalk
  10. So yep you’re right. That tube may be hard to find. I might plastic weld it. We’ll see. At this point I don’t see it being an issue as the part the tube goes over, is long. Should be ok. Sent from my iPhone using Tapatalk
  11. 10-4 I’ll see what I can do. Thanks sir! Sent from my iPhone using Tapatalk
  12. Hey guys, so I only have 2 oxygen sensors from what I can tell. Both are on the y pipe just below the manifolds. I would assume these are both upstream sensors? I have a p0134 for a bank 1 sensor 1 no circuit activity. I already replaced the passenger side. This appears to be the driver side one. Truck has no cats... so no downstream sensors. Ac Delco 213-941 Side note: I replaced the o-ring on the oil filter adapter that was leaking, no more leak! Sent from my iPhone using Tapatalk
  13. What sensor and line is this? Looks a bit frayed where it goes into the sensor which is on the intake. Sent from my iPhone using Tapatalk
  14. Looking closer, I get how these are sold... I have to transfer over the tubing for the bypass hoses to connect. Makes MUCH more sense now. Question is... do I want to spend about $130 more for the OEM one.
  15. This is the video I found, super helpful on the overall process http:// Sent from my iPhone using Tapatalk
