    Driveline Vibrations---Possible Driveshaft Issues?

    I'd be looking for a bent wheel or problem with a tire before starting to replace driveline parts that are likely still good.

    Considering a 93 K2500

    I need to clarify, the fuel injection changes were ref to 7.4L TBI. I don't believe the 5.7L is significantly different from earlier. They tweaked the Intake Manifolds and TBs to improve the fuel distribution and atomization during the era. 94 and 95 454's use a linear feedback EGR valve and...

    Another K2500 Suburban...

    Niiice Truck ! Mahe sure to change the intermediate steering shaft with rag joint. There's the slop. My writeup is on Amazon for the Dorman product.

    Considering a 93 K2500

    IMHO You're going to be better off with a 1995 2500 with 8 lugs, unless you do no towing, then 1500 OK. 1994 and 1995 FI system is different improved than 1992-1993. Everything that was going to be fixed for that era was fixed BY 1995. 1996 Vortec new, not a good year to own vs later.

    Another header post

    A true dual system should be 2.5". 3" won't help. I use Magnaflow stainless mufflers. Endless debate on X pipe but I don't think its needed on this use case. "Most of our techs agree that a street application 350 will benefit well from a header with 1 1/2" to 1 5/8" diameter primary tubes and...

    "Stock" 1991 K2500 5.7L V8 fails smog with unburned gas at exhaust.

    It won't run right without an O2 sensor. CAT output is not monitored. I'd begin by changing the MAP sensor and all the hoses associated. Next, the TPS throttle position sensor. These are both critical. You must replace the cannister OR block the port where it connects to the TB. Make sure...

    Temperature Sensor/Gauge

    That yellow line is about what I get using a 180F thermostat. Up at least one small grad for 195F.

    Correct geometry for 700r4 in a 350 carb set up

    There's a release tab on the throttle sense cable to the trans. What I always did was release and pull so the cable was too short. Then manually move the throttle all the way open, which will pull the sense cable into proper position. Release tab is back by the mount.

    Difficult to find Engine Stumble - Set Timing Connector 1995

    I think I'll solder it tomorrow just so everyone can rest at ease. This was used when I changed the entire ignition system including the distributor, which was an absolute ***** to stab. The 454 TBI gets 4 deg BTDC and you won't need to check it for years. I used a long 1/4"extension and MAC...

    Difficult to find Engine Stumble - Set Timing Connector 1995

    I'm an Electrical Engineer with 40+ years of experience. The wire nut is absolutely fine. Alternatively, just solder it and cut it off fresh every time its needed. There is no reason whatsoever to use a whether-pak connector. This is why I added 8" of wire. Fresh cut and nutted or soldered...

    Camshaft decision help

    TBI doesn't like a lot of overlap. You are dealing with a speed-density system not mass air flow. High lift is OK. Crane Cams used to make (and may still) a series called CompuCam for TBI. The other place I suggest looking is Richard Holdener's videos on YouTube. Look for videos revelant...

    Need help with ac

    Lol I just went into a '95 and was able to extract quite a bit of leaves and debris from the evaporator area. If your mode door works Ok this might be worth a try. This requires removal of the glove box door, the ECM, and the blower. While the blower is out, clean the terminals where the...

    Brakes and powersteering both out

    Must have low pressure. Check the fluid level first. I'm on my second PS pump and 3rd Hydroboost unit at 160Kmi. My hoses are showing some leak-through. I had a mechanic do the pump because a puller is needed. Did my own HB. If you tackle HB there's a spring clip you won't want to lose.
