    What would be a full vacuum line replacement?

    I have not run a smoke test but I think replacing the rubber and plastic parts can't be a bad thing in this old truck. Can anyone give me some advice on making sure there's no vacuum leaks? I definitely don't know this well so your expertise is really valuable! From what I found researching...

    Will someone help me interpret my TunerPro output so I know if I should load the parts cannon?

    These are all so helpful thank you! The computer is showing lean, and I have learned from y'all that lean can still have an exhaust smell. I always thought that exhaust smell that smells like the local drag strip was running rich. I have ordered some parts and I haven't put anything on...

    Will someone help me interpret my TunerPro output so I know if I should load the parts cannon?

    Thank you for that! The details are all very helpful as I'm working through this. I really need to figure out the fuel pressure situation so I can give a realistic answer on that. My answer currently is "I have no idea" so I need to find a way to read the pressure. Hopefully one that doesn't...

    Wow that's GORGEOUS! I'm not trying to do anything performance related and I still want that just because it looks amazing!! How much would you say the parts cost to add in the pressure sensor and regulator?

    I will check on that, just the coolant temp I'm looking for? And thank you for NGK suggestion....now I'm debating if I want to do a 3 write conversion!

    Where and how many O2 / oxygen sensors in my 1990 V8 5.7L? (verifying what I see in the Chilton)

    Thank you all! This has been a huge help!

    Thank you all for the help. I have read the fuel filters are notorious for getting clogged so that's a piece I want to do also. Is there a fuel pressure sensor or meter that you used and would recommend @Sabinoerc

    Haha that's great and I definitely will!

    That's what I'm thinking....it shouldn't hurt to have a new one and it's pretty cheap. Now it's just figure out the bosch vs AC delco debate.

    This is all great information and a huge help to someone that's new to this truck and engine. It seems like the 1 O2 sensor is probably the case in this truck, but I'm going to try to crawl my big butt under there and make sure I don't see anything else!

    Will someone help me interpret my TunerPro output so I know if I should load the parts cannon?

    This was just me driving. It normally. I was finally able to get the scanner hooked up to the computer. So I just took it on a ten or fifteen minute ride. I just recently bought the truck. So I don't know exactly how old the O2 sensor is. But I would imagine it is probably a little bit older.I...

    Will someone help me interpret my TunerPro output so I know if I should load the parts cannon?

    I thought I saw that it was lean in the output also! I'm glad I'm not going crazy. It absolutely doesn't smell lean...I wonder if the O2 sensor is shot. I don't believe I have a device that can write to the chip, unless it's extremely basic and done through the ALDL like I pulled TunerPro but...

    Will someone help me interpret my TunerPro output so I know if I should load the parts cannon?

    Thank you so much in advance y'all! So I was able to get TunerPro RT working and I went for a 10 or 15 minute drive in the old gal. I did not have any codes when I checked with the paperclip method. Some of the "issues" that concern me: - Pretty strong smell of "running rich". I hope this...

    That was part of the reason I came here to ask, the 4.8L engine definitely seemed fishy. I searched that link previously (and just went through again to make sure) and they don't have the 1990 manual unfortunately. I would much prefer those! Thank you for linking that I think it's great...

    Hi everyone, I just want to double check and verify what I'm reading in the Chilton manual for this truck. I have a 1990 GMC SIERRA 1500 SLE, 4WD, 5.7L V8 TBI. I don't know the transmission that is in it (I hope I'm giving enough information here). The manual says : "The oxygen sensor is a...
