    2003 Tahoe 32”/33.5” with mcgaughys 3/5 drop..best way to level?

    I’m kinda new to suspension mods. What’s the best way to lower the rear so the truck sits level? I’m also in the market for new wheels and tires. Any recommendations for online sources where you maybe can see a pic of different wheels on my truck?

    2003 yukon repairs and mods and wheels

    I thought about getting some factory wheels and checking if my local powder coater can match the color of the exhaust tips. The only aftermarket wheels I’m finding are black or bronze. I really like the color of the tips and think it would look good on wheels.

    2003 yukon repairs and mods and wheels

    A few plans I have for my Yukon...... Both dash brake lights are on. Code says brake control module. Thats getting replaced asap. I want aftermarket wheels, but holy crap there are 100s to choose from! Tried the Tirerack site but it doesnt offer a pic of 03 Yukon to get an idea of what they will...

    Horn/panic mode malfunctioning

    I thought about that the first time. But the second time I was 100 miles away from it when it did it.

    Horn/panic mode malfunctioning

    My panic mode has started to randomly activate, sounding the horn. It’s only done it a couple times to my knowledge. But I’m afraid it’s going to get more frequent. Has anyone had this issue?

    Misfire and no power....

    It definitely fixed the problem. Been running great until today. Parked it Saturday night with no issues. Tried to start it today and it wouldnt start. Tapped on the gas tank and it started right up. Thats pretty much the fuel pump needs replacing, right?

    Cutting them out for now to get going. I’d like to a new system this summer. But not quite ready yet.

    Wow. That sounds like my luck man! We found part of my issue. Cats are definitely clogged up. Once that’s resolved we’ll see if anything else is causing problems.

    Not yet. The shop I took it to has not impressed me so far. He’s had it since last week and hasn’t really done anything. If he doesn’t at least have some sort of diagnosis by tomorrow afternoon I guess I’ll take it somewhere else.

    I threw in the towel today guys, and took it to a local shop. Hopefully I might hear something tomorrow. Thanks for all the info!

    Another newbie question. If it turns out to be the cats are clogged. Can I do dual exhaust and eliminate the Cats altogether? Or is this newer stuff not suitable for that?

    Just random misfire code. And was getting the mass air flow sensor code. Replaced it, now just the P0300.

    I think I saw 1A Auto had a full set for $160 or so.

    I’ll recheck them. I was wondering if the heat soak would be an issue.

    Yes sir.

    Misfire and no power....

    I checked the exhaust temps at the point of exit at the head. Seems like a wide range to be honest. Almost makes me doubt my thermometer is working properly. Driver side front cylinder 287 second cylinder 347 third cylinder 333 rear cylinder 311 Passenger side front cyl. 288 second cyl. 214...

    Probably a dumb question. But does it need to be at full operating temp to check them all? I would think so but I’d rather ask and know.

    I replaced the plugs and wires this weekend. I used Taylor wires and AC Delco plugs.

    Misfire and no power....

    If the cats were clogged to the point of causing this much of an issue, would it sound like it has an exhaust leak under the hood? It’s got that steady poofing sound when idling. That’s a silly way of describing it but I’m sure y’all know what I’m referring to.

    Misfire and no power....

    I checked the exhaust temps at the entrance and exit of the Cats. They were within 15-20 degrees or so. Is that a reliable way to check them? I checked that the coils are firing. I checked the injector harnesses with a noid light. All were good. Last night unplugging some of the injectors...
