    Welcome! You’re about three hours from me so I can keep a lookout if you need something.

    90 Suburban ECM Fuse Popping

    You mentioned hitting a bump and everything went to hell so try this. I was having the same issue on my Caprice this summer. It took me three weeks to nail it, but my ESC wires were too close to the manifold, and the insulation was flaking off. Everytime the car flexed around or the air hit the...

    Truck won’t turn on

    Fusible links are the main concern when that happens, but I’ve done it on a dual battery vehicle where the second battery goes in backwards, and I wasn’t paying attention. It was only for a second, and all it did was shoot molten battery terminal at me. The battery was still good, and nothing...

    Question about pulling to left while braking.

    He’s saying it’s the former, but what would say if it was the latter? Rear brakes?

    New Daily Driver (Caprice)

    Ooh, those hubcaps are doing something for me.

    New Daily Driver (Caprice)

    It’s bad enough, but you’ve got it lifted past the skirted rear, and it looks so much worse. Let me run some other ideas by you.

    Speedo gone wild

    If your speedo head is working properly, the AC Delco is okay. There’s a company that builds them in Denver, Speedometer Cables USA, that swore to me up and down that their design rivals the OEM from this period. It sounds like they’re based on an older design. Oh, and here’s the advice he gave...

    Speedo gone wild

    Really crappy cables that don’t spin truly will do that, too, but my money’s on the binding. I’d mix some denatured alcohol and graphite powder together, pull the cluster, hook a drill to the transmission end, and pour the solution down its gullet while spinning the drill to work it down.

    1990 454 SS Pickup

    This is nice. I agree on the bezel. Had it been done poorly, that whole concept could have quickly flown south for the winter, but it looks like it was done with care. I would normally want to go back to the Delco tuner/display and EQ/tape deck, but the work here was also done well, and I don’t...

    New Daily Driver (Caprice)

    That’s pretty nice. I really like those rally wheels they’re probably my favorite for GM cars in general, but I can’t wrap my head around them being on a sedan. Maybe it’s a taste acquired with age, but I like the police look on these. And yeah, the white letters do have to show to complete the...

    New Daily Driver (Caprice)

    Good idea. That would help give it a meaner look.

    '05 Chevy Malibu

    Oh, I was saying I care about you! But I’m skeptical of some of GM’s quality criticisms around that time. I just drove my grandma’s ‘01 Pontiac Grand Am 2.4 Quad IV/4T40E yesterday, and that sucker runs like a top. It’s pitiful cosmetically but pretty tough where it counts. I’m under the...

    Ole reliable being reliable as always. I’ve had a few lightbulbs go off in my head of mods that I’ve started to do/I’d like to do. 1. Get my damn aux. cluster built and installed: I’m not gonna replicate the 9C1 location because I don’t want to mutiliate the dash and have to move things...

    New and a load of help needed

    Definitely need those pics, and if you don’t have a vacuum diagram somewhere under the hood, @Craig 85 will have the correct one for you. But was that a typo in the initial post? You said a TH250 transmission, or did you mean a TH350? If the former, I’d be real careful with that thing. If the...

    '80 K30 cruise control

    No, I was talking about your jerky cruise issue. I know a cheap, junky cable will confuse the Hall effect sensor on the 84+ trucks, but I don’t know if a bad upper or lower cable would do the same to the transducer.

    '80 K30 cruise control

    Make sure the vacuum lines related to the servo aren’t cracked, and make sure your one way check valve coming off the intake and the vacuum storage canister are in working order.

    WTB: TBI Distributor and Ignition Coil

    Does anyone have these two items to part with at a “square” price?

    Welcome! That’s a very nice looking truck you got there.

    700r4 3-2 shutter

    The torque converter in my Caprice is well past its prime, and it’ll do this sometimes. The clutch inside shudders and chatters sometimes. Worst locked up in 4, plenty in 4-3, but sometimes even in 3-2. I put the red shudder fix stuff in it, and it helped a lot, but if you have a bad TV for...

    Carb to TBI Conversion

    I think you could find a buyer for the TBI setup. It’s not a super lucrative market, but there are enough people who want TBI or have TBI systems that are so hacked up, they want a fresh start so they can keep it TBI. That being said there are more people going simpler than more complex. Either...

    Engine overheating

    Yeah, I’m against the cooler stat, also. Get you a little Preston’s flush kit from Walmart and backflush your cooling system. It’ll tee into your garden hose at one of the heater hoses (can’t remember if inlet or outlet at the moment). As far as a cleaning agent goes, I’ve heard of Borax, never...

    breaking in a fresh 350

    It’s either a cooling problem or a friction problem. If the water jacket in that head isn’t somehow blocked causing a localized cooling issue, your valve lash could be too tight, you could have a lifter issue (assuming hydraulic not solid), or the cam bearing could have been improperly clocked...

    Trucks with factory Blue

    I love this scheme from our old ‘86. I had planned to do this to mine one day, but I don’t know how it’d look with the grey interior.

    ***SOLD**** FS: ‘93 K1500 Z71

    Forgot to mark it here, but I sold it a couple weeks ago for $1600. Just got tired of the tire kickers, wannabe traders, and low ballers. Anyway, if a mod could mark as sold, I’d appreciate it. @bucket @Old77
