    3/4 ton shocks on 1/2 ton 96 yukon

    I did this for my 93 2wd suburban. I put in 3/4 ton shocks. Really didn't do too much, but it did level out the ride so it didn't have that 2wd 'droop' in the front. Rides about the same. Not sure if you have ever changed springs before, but do your research and be careful. I heard an old...

    Please help! Running poorly. 454 7.4 94 suburban. No power. Need to tow and go!

    New thread? I did something wrong. Just being a newb, maybe its cause I'm Canadian. Dunno. Anyhoo, the spark plugs were an inch longer and the gap was at .054 as opposed to the .035 they should have been. It would start quick but like a boom, as if the cylinder was filling up-like you...

    -as in previous threads, running a limping town vehicle. Leaving in a day. Going to try a decent mechanic stateside. Flat around here, so going slow is possible till can fix up. Any help appreciated. Will post more about my vehicles to hopefully help others once they are running better...

    Okay, going to try the throttle linkage trick. Light still on, stalled today after running 5 minutes. Replaced spark plugs with platinum, new cap and rotor. Previous owner had massive spark plugs with an enormous gap. Like, .054. Could be that running that way for so long led to carbon and...

    This to me, sounds like the most plausible explanation for the suction feeling. As far as scan tool. Hard to come by in these parts. Many garages who used work on and safety inspect these vehicles have relinquished their small vehicle inspection licences and gotten rid of old diagnostic tools...

    Checked pintle size, confused the parts counter people. Appears they did not know as the specs did not indicate. I appear to have the right one. I'll have to re-check to make sure. Thank you.

    So, added seafoam, changed fuel filter, also filled tank and added octane boost. It runs like it would rather be a Tesla. Taking it to an old school pro-rare in these parts to give it a throrough looking over. Another old timer told me that these engines were prone to intake manifold...

    Well, not sure about the issues with the 2500. Sure, it is a no brainer towing with that one. The numbers are tight. But I think that is good for me being diligent in preparation and not bringing too much stuff. Plus, once we're camped, I'd rather drive around in the 1500. Gas mileage..

    Thanks bud, appreciate the input. I have driven throughout western canada, several times, I mean many, many times. Familiar with those roads and the driver's and as know in BC, those with beginner tags-Alberta plates. Wind is my worst enemy. Just don't know the capabilities of that vehicle...
