    Base difference.... Another mirror thread

    I seem to recall reading somewhere a few different descriptions of the differences, but can't find anything that verifies what I'm recalling. I'm thinking it was a matter of one of the bolts not being in the same location, which I can fix with a drill bit, and that the base was shaped slightly...

    Trail Ridge power tow mirror question:

    I think you'd be fine. I can't imagine it being so fragile that adjusting it once (or twice, ot ten times) by hand would be an issue. If it was that fragile we'd have heard about a bunch of them being broken going through the automatic car wash

    Base difference.... Another mirror thread

    I want to put some towing mirrors on my '96. I've found somebody selling a pair, and he says they fit 2000 and later trucks but won't fit his '97. I know the bases are different (but similar) between the 800 trucks and the 400's, but the difference isn't obvious to me. I tried searching and...

    Fouling 2 plugs

    Got it put together and it ran marginally better, but still misfiring and fouling 3 & 5. Been screwing with it for a couple days and ultimately decided to go back to the last part I replaced, which was the cap & rotor. I got them from AutoZone, and got the Duralast Gold with the lifetime...

    Fouling 2 plugs

    I just got the guy at AutoZone to check it. I've been looking for a scan tool, but haven't got one yet. I'm not positive it's accurate, but I've had it for years and used it on other cars, mostly my Volvos when I need to find out if I blew another head gasket, and the numbers I've gotten in...

    Fouling 2 plugs

    I put a gauge on it to check the fuel pressure. When running, it's showing 50 psi, and when I shut it off it holds that pressure for at least a couple minutes. If I had an injector or a line that was leaking, that pressure would drop, right?

    Fouling 2 plugs

    I swapped 3 and 5 with 1 and 7 and it's misfiring as soon as I start it up. There's no time period where it runs ok, waiting for the plug to become fouled. I thought maybe I got a defective distributor cap, but I pulled each wire off and checked with a plug and they're firing.

    Fouling 2 plugs

    I've got a '96 C2500, 5.7, and it's misfiring. CEL is flashing, but the code is "Random Misfire". I pulled the plugs and #3 and #5 are fouled black. The rest look good. Gap is good. Did a compression test on that bank and I get 200, 195, 190, 195, so I'm ruling out head gasket. Plus, I'm...

    Brake booster - 96 vs 97

    I need a brake booster for my 96 (JB7 brakes). Cheapest one on Rock Auto is $80, and a week waiting, but my local wrecking yard has a 97 (also JB7) with what looks like a new booster that I can get today for $20. Interchanges that I'm looking at list the 94-96 as a different booster than...

    MAP issues (P0108)

    It's the hose that came with the new pump, installed maybe 3 weeks ago. It's all soft and spongy. I've got some fuel line I can replace it with, but is there a special hose for submersion?

    MAP issues (P0108)

    6 hours and a tow bill later and it seems the fuel pump has now blown a hole in the hose

    MAP issues (P0108)

    Yeah, the hose came off. The plastic clamps were still tight, but they're plastic clamps. Replaced them with metal. The lower metal bracket where the pump sits is bent slightly. I don't recall exactly what the issue was, but I spent maybe half an hour putting the pump in, taking it back out...

    Pretty sure I found the problem. See if you can spot it

    MAP issues (P0108)

    I'm generally pretty careful about fuel stuff. When I pulled the pump I blew all the dirt off the top, scrubbed it with a small brush, blew it off again, then took the pump out. Inside the tank was very clean. Just put a filter in it, just because they're only ten bucks, and cleaned all the...

    MAP issues (P0108)

    A few weeks ago I replaced a dead Delphi fuel pump with a new Delphi pump. I checked the fuel pressure today and I'm getting this at idle. Granted, it idles rough, and it dies after 8 or 10 seconds, but I thought these trucks needed at least 55 psi to run at all. At least that's what I recall...

    MAP issues (P0108)

    I haven't. I will. It's getting to the point where it barely runs now, so I'm checking every plug on every sensor. It won't rev now, and idles for maybe 4 or 5 seconds and dies. I keep getting the P0108 code (MAP sensor), but I've swapped in 4 MAP sensors with no change. They're used, but...

    MAP issues (P0108)

    I pulled the hose off the brake booster and it was holding a vacuum. I presume if I had a vacuum leak, the vacuum in the booster would have bled off, right?

    MAP issues (P0108)

    Cleaned the plugs, tightened up the cap, still runs like crap. So it idles ok, but I've also come to realize that if I hit the throttle slowly I can get the RPM's up to 3 or 4k no problem. And if I mash the throttle at 3k, it'll jump. But if I mash the throttle at idle, it dies. That's got...

    MAP issues (P0108)

    For the sake of anybody searching in the future, best I can find is that the original cap screws (GM part #10475922) can be replaced with an oversize screw (GM part #10457666). I would assume that just makes the problem bigger at some point. If the distributor holes stripped with small bolts...

    MAP issues (P0108)

    I checked the plugs and they're black. Wires look good, but I found the distributor cap very loose. Apparently the screws that hold it on have stripped the holes in the distributor, so I couldn't tighten them. I seem to recall reading something about this being a common problem, and oversize...

    MAP issues (P0108)

    Messing with the truck some more and I briefly got a code for the TPS (P0122) along with the MAP sensor (P0108). I cleared the codes and only the MAP sensor code has come back. Thanks to a liberal return policy at Pick-n-Pull, I now have a collection of 4 MAP sensors and 3 TP sensors. I've...

    MAP issues (P0108)

    I searched...found threads that just died (I hate that...post what you found), and threads by people who were chasing multipe codes. I've got one code. So my truck ('96, 5.7) was running fine, then suddenly started popping and backfiring a bit, and generally losing power. An hour later it...

    Fuel pump works...then doesn't.. then does...then...

    Well, I can't take all the credit. Or really any of it. I got the truck in 2015 with 425k on it from a guy who owned a towing company, and this is what he told me at the time.... Towing guy did some work for a mechanic who owed him money. Mechanic guy used this as his mobile repair rig, and...

    Fuel pump works...then doesn't.. then does...then...

    Yeah, I forget the GMT400 line goes back to '88. Somehow I have in my mind that it's just 96-99. I'm not really a Chevy guy, just a guy who happens to own a Chevy. Probably doesn't much matter now, but for anybody searching in the future it's a '96 2500HD, 5.7, updated spider and 140a...
