    1987 454 TBI stalls at idle after a short time

    Hello again, I have this new to me 1987 454 TBI suburban that I’ve been chasing problems down in. Today’s issue is stalling after a few mins of idling. The previous problem was power being way down, to the point where it would max out at 47 mph and you could only use literally the first 1/4”...

    Thoughts on how to recover from a slightly cross threaded spark plug threads in head?

    Was installing a DUI distributor, coil, wires, and plugs. Got distributor and coil installed and old plugs out. Started installing new plugs and hit a snag. 454, #8 rearmost passenger side. Felt like it went in ok a few turns and then I started tightening with a ratchet, but it didn’t feel...

    Can you let AC flush sit in lines and hoses and blow it out later?

    So I’m replacing most the the AC stuff in my ‘87 suburban R20 with rear air. Condenser, front evaporator, compressor, dryer, rear expansion valve, etc. Basically everything except lines and rear evaporator currently. I took off the rear expansion valve from the evaporator, and it looks...

    Vintage Air Gen V (5) or replace existing compressor, etc., for 1987 R20 Suburban?

    Hi all, I bought this clean 1987 R20 454 Suburban a couple months ago. The AC didn’t work, and when I hooked my gauges up only had about 10 psig on the low side. It had r134 fittings already, but I went ahead and replaced the schrader cores and replaced the orifice tube and o-ring. Pulled a...

    ‘87 454 TBI, NO Fuel spray, HAS fuel pressure, has 12v @ injectors, has spark

    Drove the truck for an hour to pick up my kids Sunday. Turned truck off, kids put their stuff in, daughter went to start truck literally 2 mins after I turned it off and it would crank fine, but not a hint of fire. Ended up having to get it towed home. There is ZERO fuel from the injectors...

    1987 454 TBI down on power, runs good otherwise

    So I bought this 1987 R20 a couple weeks ago, and it seems to run well except it’s down on power as rpms rise. Pulls pretty strongly from a stop, but as revs rise it stops making power. And if you are driving and cause it to downshift, it immediately does nothing. Makes noise and seems to...

    Retro Belt 3-pt belt install with pics

    I installed Retro Belt 3-point belts up front in my 1987 R20 Suburban so figured I’d post some pics of how I installed them. I used a pic from below through the original mounting nut (my truck was missing the inner receptacles), then used a razor blade to cut the carpet and some needle nose...

    1987 Suburban BUCKET seats inner 3-pt buckle floor mount location?

    Hi all, we just bought a 1987 suburban last weekend. It has front bucket seats with the center console. Someone has redone the interior, but they did NOT put the inner seat belt buckles back. I bought new, aftermarket 3-pt belts, but can’t tell where the inner buckles mount on the floor...

    ‘87 454 R20 eye watering exhaust w/ windows down

    Hi all, we just bought a really clean 1987 454 R20 with about 80k miles. Driving with the windows down is brutal after accelerating and coming off the gas. Made even worse if the tailgate window is open. Like, so bad your eyes burn and water so badly you can barely see. It has true dual...
