    Code thrown but not for my year/MAP issue

    @AuroraGirl the threads were coated with very wet oil, not as dry as in your plug on the left. There really wasnt any oil on the smooth silver portion that's outside the head when the plug is installed. Maybe the taper is decent? But with the threads being so coated you could be onto something...

    Code thrown but not for my year/MAP issue

    I sure can. I don't drive it a lot yet so it might take a minute but I definitely will. They were way worse than the one on the left it your picture.

    Code thrown but not for my year/MAP issue

    The wires are brand spanking new blue streaks with a couple hours run time. Put new ones on in an attempt to sort out the miss. Spent a good deal of time separating them with a zip tie loom. I had found one of the old wires kinda burnt. I tested them for resistance and they all were fine but it...

    Code thrown but not for my year/MAP issue

    @AuroraGirl running them at 35. And I mean AC Delco CR43TS and CR45TS, fingers just got lazy. I may try the anti foulers if the plugs die too quickly.

    91 burb runs terrible in reverse

    I did a bunch of looking and wire wiggling. Didn't find anything that stood out. I did however find a couple spark plugs were oil fouled dealing with other issues. That was the miss I was feeling. Cleaned the plugs and it stopped acting weird in reverse. I can't say if it was the wire wiggle...

    Code thrown but not for my year/MAP issue

    A little update Still running and driving good so far. Took it to cut some wood and when I got home I checked #4 and #6 plugs again. I wanted to see how quick they got covered it oil. After maybe 20 miles and 20 minutes of run time from the trip they were looking about ready to foul. Even the...

    Going Poly

    I had to do every kind of destruction to get the last set of oem style I removed. @SquareRoot have you ever tried Delrin? I've never tried to make a leaf spring bushing but you can buy blocks of it to make bushings out of it.

    What have you done to your square lately??

    Trying my hand at making a rear heater box for my Suburban. Making kind of a prototype first so I can figure out how I want it. Uses all the original parts. Just want it to be more sturdy so it can't get hit by stuff and broken.

    Front Fender Well Inspection Covers?

    My replacement LMC inners have these attached. They're tacked on.

    Code thrown but not for my year/MAP issue

    Gave everything a look over and took it for a drive. No check engine light still so the map is either good or intermittently good. My kid came by and I took him for a test spin and to get some gas. It ran rough and had no power. Like foot to the floor, didn't want to downshift, 1/4 mile of...

    First time replacing intake manifold gaskets

    OP, when I was first learning my old man taught me to write information on the inside of my hood. That way I could pop the hood anytime and be able to see firing order, the rotation of the distributor, part numbers for oil filters and oil capacities and other specific information if I forgot. It...

    Code thrown but not for my year/MAP issue

    Can the computer tell if my cat is clogged up? I took a temp reading before and after the cat on the pipe and they were pretty close. Its the stock cat I think. I ask because the exhaust smells clean as hell most of the time but occasionally it smells kinda foul. Seems to be smelly when it...

    Code thrown but not for my year/MAP issue

    I have. Not running it held vacuum. I also activated with a mighty vac while at idle and the engine fell on its face. I was for sure it was opening it at idle causing it to have a vac leak. Symptoms seemed to match. Did have to replace the EGR solenoid a while ago because it tested bad. I...

    Engine won't get up to temp

    This probably won't help your problem but I've heard of a 'cold weather package". Wonder if any of those items would help. My suburban spent a lot of its life in Canada/Alaska and it came to me with the smallest radiator I've ever seen in a square and a ridiculous looking 3 blade fan.

    Code thrown but not for my year/MAP issue

    What did I say? It's a win until its not.. Back to issues. Went on a quick trip for some errands. 10 minutes of driving then sitting in a parking spot waiting on the wife. I'm waiting sitting at idle, foot off brake, for 3-4 minutes. Suddenly the idle drops and the engine runs rough. Check...

    You could just move your front hangers or am I missing something?

    Transmission lowering?

    Dang it, I just realized I didn't come back to this. I did end up taking out the spacers and putting them back in OEM location. I don't notice any differences. When I was doing research on this I found something that I didn't see often talked about. Lots of people were talking about issues...

    Yukon Grizzly Locker MUST READ

    I put a grizzly in the back of my Wrangler and liked it a lot. Decent road manners for an automatic locker on a short wheelbase rig. Pretty quiet. Barely heard a noise out of it. It was super predictable. If I was on the gas then it was locked, if I was off the gas then it was unlocked. YMMV

    Code thrown but not for my year/MAP issue

    Yesterday took it for a 30 minute drive with some big hills and whatnot. No lights, no issues. Another 30 minutes drive later with no issues. Calling it a win.

    Benefits of longer leaf springs and suspension lift vs blocks

    Chuck the body lift and go with a 4" lift instead. Alcan or Deaver probably have the best leaf springs. Or talk to ORD about getting one of their kits which are finally tailored to a square body. There will be a few things extended that won't need to be anymore like linkage for transmission or...
