    Drivetrain locked up in truck! & Transmission interchange question??

    Hey guys... Driving thru a parking lot yesterday and got a pretty nasty grind for about a second or two then complete driveline lock. Removed the driveshaft and truck was able to roll. I have been hearing nasty sounds from what I was certain was transfer case. What's the word on those seizing...

    Transfer Case woes

    a little shy of 260k miles. I have the 4-option switch to the right of the cluster with 4WD-Auto option. Do you know which one this might be?

    Transfer Case woes

    Hey guys, there is a pretty gnarly sound coming from my transfer case. It's pretty much sounding like the world is ending inside there. I'm not sure if the chain has stretched or if something broke. It runs/shifts/drives fine with the exception of the case. I hardly ever use 4WD and drive 99%...

    Odd condition, random misfire, no power under load, bucking, dying...

    The truck seems to be re learning LTFT and is running better. Still not 100% but 90%. Will still buck on occasion but I believe that has to do more with the LT4 hot cam and tune than anything. Everything has stayed in order for around 150 miles now and even got it inspected yesterday. Finally...

    Odd condition, random misfire, no power under load, bucking, dying...

    Cleaned MAF last night with MAF cleaner, disconnected battery and started re-learn process. Seems to shift a bit nicer but still got bucking off idle. Not sure if that is still the original problem or just how the truck behaves during the re-learn. I'll move on to the TPS

    Odd condition, random misfire, no power under load, bucking, dying...

    Hey guys. Chasing an old condition that has now come back with a fury. The truck has a chronic low/no power condition on warm start, off idle. If I'm trying to exit a parking lot, or turn across an intersection, this can be a bit perilous. Essentially, the truck has no power when applying...

    Destroyed power steering pulley.

    Hey guys just curious if there's any good ways to get the PS pump off without removing the pulley? I pretty much just destroyed it using a puller tool. The snout has pretty much sheared in half. Are the bolts behind it accessible enough to get out with fingers? I can get a wrench on them and...

    Lower Control Arm Bushings

    Hey guys just curious if they have discontinued the lower control arm assy with new bushing? There is nothing available for 4WD on rock auto. Is pressing the old bushing out and pressing new one in something a shop can do pretty easily for low cost? Thanks, Brandon

    Location and placement of spark plug wire holders/looms

    Was curious if anyone had a picture/s or diagrams of where the spark plug wire holders sit and how they're oriented? Engine builder left all of mine off and I have burnt 3 wires :(.

    It's LS time...

    Hey guys over the last 2 years I've been riding around on my L31 rebuild, which I posted about in this section... But I think the time has come to jump over to the LS. I acquired an L76 block for a decent price this weekend and am planning an LS swap into my daily 1999 2Dr Tahoe. I don't want...

    96 Tahoe Fuel gauge/sender

    Sorry it was a busy weekend and I didn't get a chance to update. It's FIXED! ECM-I fuse goes to injectors and ICM among some other things. Unplugged the injector and ICM harnesses and keyed on and fuse was still good. Plugged in the spider and it blew. Got the intake hat off and got the old...

    96 Tahoe Fuel gauge/sender

    In the event that it is a pump I do have a full tank of gas, doh. I tried siphoning yesterday but it seems like the line i was using was hitting some sort of kink or something and it wasn't going into the tank. Is there some tyupe of anti siphon device in there?

    96 Tahoe Fuel gauge/sender

    I'm jumping on this thread too... yesterday while accelerating up an onramp to the highway under load, the truck shut off completely. Cranks solidly with no start. My fuel gauge is absolutely dead like the OP picture. Key on ign off, I can hear no pump priming or anything. Had been having a...

    Misfire on #4 cylinder + evap emiss. code too

    Well, got the diagnosis back from the shop: Bad injector driver in the PCM. Apparently the #4 injector is not firing from the PCM at all. I guess they got it to fire by using a pulser or something like that. Which brings me to my next question... This is a Black Bear module I got in October...

    Misfire on #4 cylinder + evap emiss. code too

    I have been getting P0304. SES light is solid @ idle and around Evap sensor was fixed. Broken disconnect @ the valve by the intake mani. Pulled #4 plug and it was pretty gnarly (#4 on left, #2 on right). Checked all 7 others and they all pretty much looked the same as #2. Replaced...

    My project...

    Well I replaced the IAC valve and it started right up... About a week later, it's back up to its old ways... This was a cheap Oreilley IAC that I put in. Could it be bad already? Ac was fixed with a couple of cheap valves and fixed a major oil leak. Seems the installer neglected to put any RTV...

    My project...

    Well had it now for almost a month and everything is smooth. Only kinks I can think of is that it almost wants to die on startup and after shifting into drive. Could this be a tune issue? I have a Blackbear PCM. Also seems the alternator pulley or bearing is bad... Gonna replace that this...
