  1. Something about grounding a pin on the OBD connector, but I can’t find my bookmark.
  2. Jack up the rear and turn the driveshaft to see if its your diff. Does it bog in reverse or rev freely?
  3. If I’m understanding your description as popcorn being random and not evenly timed, I recently developed something similar on my 95 350 TBI. Mine seems to happen only when engine is warm, AC is on, and in Drive with the brakes on (at a traffic light for instance). It stumbles just briefly but randomly (like popcorn?). I was thinking something with the Idle Air Control (IAC)? Suggestions appreciated.
  4. Post a parts list - I have a 95, need to do the same. I was just looking today at https://www.lmctruck.com/suspension
  5. lmctruck.com has some good exploded views. You can order a paper catalog for your specific vehicle family.
  6. I don’t know what I’m talking about, so take this with a grain of salt. Could it be related to the speed sensor?
  7. Well, the cap color is more accurate than anticipated. The Prestone DexCool (left) is definitely orange, and what’s in the reservoir(right) is pink.
  8. Thank you! Why the cap and colors on the jug wouldn’t match the contents boggles the mind. Am I the only one who thinks of antifreeze in terms of color?
  9. If you unplug the line and it “fixes” it, that doesn’t mean your brake booster is bad. But if this is a new symptom, I can’t think of anything else that would be the culprit. You should expect to see the Rpm’s react slightly to the brakes, but it may something else. Does it do the same thing when you’re idling and turn on/off the AC?
  10. So I guess I need to break the seal on a jug of Dexcool and compare the two. Is there a pink coolant? Going by the label color, maybe Mercedes coolant? I don’t want to mix types and I don’t want to use the wrong type... everything says use Dexcool, so I guess I’m flushing if it’s not a match.
  11. Bought a used 2017 Suburban awhile back. Noticed the coolant was a little low, so I bought some Dexcool compatible as recommended by my LAP store. Before I added it, I pulled a sample and what’s in there is as pink as pink can be. The Preston Dexcool is orange. Did I buy the wrong coolant, or did the previous owner/dealer put in the wrong stuff? Do I just need to flush and fill with orange?
