    Rear Disc Brake Upgrade Update

    One issue with the E-Brake/Parking Brake is that the cable can freeze in the winter. I have had this happen on 2 vehicles in my driving career. 1 of them is my 89 GMT400. I have a manual 5 speed. While I do use the parking brake in the summer I will not use it in freezing weather. First winter I...

    1990 C1500 ABS (RWAL) removal.

    You will lose very little fluid. The line move fine. Just a little stretch of the coiled, nothing drastic. I cut the wires going to the ABS controller, staggering their lengths. Then tucked them in side the loom. Sent from my SM-G930U using Tapatalk

    XJ Steering Shaft Upgrade (88-94 Trucks) 95+instructions on page 31

    There is no extra vibration from changing out a rag joint to a universal joint. My 97 Dodge van had universal from the factory and it was lined up where a rag joint would have worked fine. The Jeeps that many of us have pulled these shafts from were also lined up where a rag joint would have...

    More than likely, that is how I got mine.

    High idle with 22 inch of vacuum

    After a long day of pulling parts to change the intake gasket I found the actual problem. The MAP sensor elbow that connects to the throttle body. Found a crack in it that also had dirt in the crack which told me it was a old crack. I had tried to pull it a month and a half ago but it would not...

    There is no button on the proportioning valve to manually reset. It should try to reset every time you push the brake pedal. Right now it thinks you have a leak in the rear side of your brake system. Make sure all your rear lines are tight. You may even need a vacuum pump to bleed the rear brakes.

    High idle with 22 inch of vacuum

    I will check both the timing and pinch off the brake booster hose and see what that does. I am starting to suspicion a problem with the wiring bundle on the drivers side of the engine block. Saturday I found the area of the engine harness that has a heat shield wrap near where the air-pump...

    High idle with 22 inch of vacuum

    Now I have also... Replaced O2 sensor Replaced the throttle body to air hat gasket. Tried a different ECM (1227747), no change. Something is causing the computer to open the IAC to 1800-2000 rpms randomly. I have gone a day or two with it behaving and then it starts idling high again.

    High idle with 22 inch of vacuum

    Random high idle problem is back and I am frustrated. Replaced the PCM temp sensor (2nd time) and its wire harness today. Bought the ALDL to USB cable and downloaded the TunerProRT, cannot get the cable to talk to the program even though the PC see the cable and says it is in working order...

    Value of our trucks

    Might double check but I think he meant that it needs a brake/tail light, not brake line. Look at the rear of the truck picture.

    High idle with 22 inch of vacuum

    Faulty PCM coolant temp sensor was the root of the issue. I need to find scanner that reads live data from this trucks PCM, for that would have saved me a lot of headache dealing with this issue. Also it was code 34, not 32, that I put in the first post.

    High idle with 22 inch of vacuum

    Disconnected the cruise control which had never worked since I got the truck, no change. Checked the IAC and no debris in the port, not even a hint of carbon coloring, this TB is the cleanest I have ever seen. How do you check to see if the IAC is fully closed? Side note: no hissing of a...

    High idle with 22 inch of vacuum

    1989 GMC C1500 5.7 with 5 speed manual transmission. Month ago got random stall like symptoms where the engine would sound like it quite running, Service Engine Soon light would come on. My OBD I and II code reader could not find any fault codes. Paper clip in the A/B pins of the ODL found code...

    The "pressure wire" is the wire that connects to the proportioning valve. For that valve senses when equal pressure is lost.

    Hey check these out greasable door hinge pins

    Though seems like a great idea I am not going to get a set. My 1977 Impala still has all the original hinge pins/bushings and none of the doors sag. All I do is as the owners manual stated is put 30 weight oil on them once or twice a year. Now my truck I have had to change both door hinge...

    Value of our trucks

    In 2014 I bought mine for a mere $200.00 in labor trade. I was quickly offered $900.00 which I turned down. The tag office wanted to charged me taxes on their value of nearly 3K and I told them NO, truck is at that time 24 years old and did not qualify for state declared tax value. I don't mind...

    Yes it is. But I suggest checking a salvage yard first. You could pay less for it. Sent from my SM-G930U using Tapatalk

    Yes that is how you check. You will be able to tell if the play is in the rag joint and or the gear box itself.

    Starting problems / gas fumes (1993 TBI)

    On the fail to start issue that happens from time to time, check that you have spark when the truck does not start. I do not think that the EVAP canister or if yours has the tank pressure control valve would cause the no start condition. I would recommend if the truck does not have spark to...

    A/C Condenser Fan/Wiring Issue, and a TPS Question...

    Never used it. Did look into it once a few years ago and if you run only water it claims to have the highest benefit about 20 some degrees if I remember correctly. I run 50/50 and it claimed to only drop it about 3 more degrees, was not enough for me to try it. I learned a long time ago not to...

    Where I live and use to live we have hard water. The former place had water so hard that radiators and home hot water tanks did not live past 10 years if they made it that long. I just do not trust tap water for anything but washing and some cooking. I do not even drink our local water (from a...
