    Riddle me this... hot start 'N dies, miss / cut out only in summer

    I haven’t had the issues since it’s been cooler temperatures. Only happens to my truck when it’s above 90° outside and truck is heat soaked from a long drive.

    Would you still get an alignment done?

    My stock keys were cranked and these were still an improvement. The new keys lifted the front more than the stock keys with bolts maxed out. I thought you weren’t supposed to run the stock keys at the “unsafe angle” when the bolts were maxed? Or is that a myth? New keys were $40

    Would you still get an alignment done?

    I replaced the stock torsion keys with lift replacements, but just barely engaged the bolts on the replacements. This raise the front end maybe an inch inch and a half and I can still get a pinky finger between the upper an-arm and the stop. The new keys really firmed up the front end as my...

    120MPH Yukon Denali / Tahoe limited cluster swap issues

    FYI I put my speedo needle on at 70mph not while driving but in driveway with rear wheels off the ground. Put trans in 3. Watched my scan tool until I was at 70 and put the needle on at 70. redid rpm in Park and held it at 2k on scan tool then pinned on needle. The other 4 gauges are correct...

    120MPH Yukon Denali / Tahoe limited cluster swap issues

    Check with a gps speedo app on your phone. Even though your tires are the same size as what the truck door sticker calls for different tire brands are slightly different overall diameter. Aka they are all listed the same size but actual size is 31.6, 31.7, 31.8. Or your stepper motor is a bit...

    changing mileage odometer cluster swap

    Thanks for posting this. I just put a 2000 Escalade cluster in my truck with the 120mph speedo and white gauges. However, the cluster glows blue instead of white. Was that standard on Escalade or did someone change it? I moved my Illumination bulbs over from the orig 97 cluster and the 2k...

    Power locks not working slow sticking free fix

    Will see how long it lasts with torn actuator rubber boot allowing dust to enter but i didn’t want to leave doors apart waiting for replacements. Also seems like you can’t beat original parts these days with all the Chinese crap that’s out there. I’ll refurbish a OEM GM part if I can instead...

    Power locks not working slow sticking free fix

    My locks were still slow until I lubed inside the power lock rubber boot spraying towards actuator. The old grease on the rods where it goes through plastic was sticky like glue. Cleans that off with carb cleaner and lubed with the 3 n 1

    Cam upgrade for 1997 Vortec 5.7 L31 with 210k

    Emailed Comp cams for a camshaft recommendation. I've been hearing complaints about flat tappet cams going flat due to inferior materials being used. Is this a non issue in a roller motor like the L31, or are manufacturers cranking out crap on those as well?

    Riddle me this... hot start 'N dies, miss / cut out only in summer

    Good questions, this always seems to happen when I'm far away from the garage, to check these questions when on the road with a hot heat soaked engine.... Let it cool off for 10 minutes and it starts and runs just fine, can idle in traffic hot with no issues. Randomly rears its head when trying...

    Riddle me this... hot start 'N dies, miss / cut out only in summer

    Well its happened again. Does not cut out when running and 100 degree temps outside like before. If you shut truck off and let it sit for 5 - 20 minutes it won't restart or will start, fire and die. If I can dance with the pedal enough to keep it going once it comes back to idle it runs great...

    Upgrading to mpfi should i do the lower intake gasket?!

    Some reviews - it runs so much better, more responsive, etc. Guessing something was wrong with original Spider injection. I’ll keep running the ol poppet mechanical injectors [emoji106]

    Upgrading to mpfi should i do the lower intake gasket?!

    Should I even bother with MPFI upgrade? 5.7 with 215k runs great. Any benefit to mpfi when the old spider is working fine? I’ve read some reviews where the mpfi caused issues when a injector stopped working. What’s the best price / place to order? Delphi or AC Delco? My truck had intake...

    96 GMC sierra p0172 and P0300 and flashing ses

    Yeah a better code reader can hopefully narrow it down. Could be a failing coil or bad spark plug wire. Have you ohm’d out all the plug wires? I’ve seen new wires have a bad one out of the box. Also see a sparkplug fail and not fire plug looked fine but code reader said misfire cylinder 5...

    96 GMC sierra p0172 and P0300 and flashing ses

    I have 212k on my 97 k1500. Original spider injectors. Runs excellent! Of course had to do vortec intake gasket. On its 3rd fuel pump. Recently replaced ignition control module since the original one was failing. Engine would cut out in rpm range and would only do it in hot summer temps. Cool...
