  1. My '15 has about the same mileage and the older it gets the more concerned I am about it's longevity. It's already had to have the AFM lifters on one side replaced and the y-pipe with the cats replaced. Both done under various warranties. I'm rapidly approaching the end of my extended warranty and powertrain warranties. I'm afraid the days of the 25 year old chevy cruising around are nearing an end.
  2. Who knows? Could be where we live (hotter climates) or how we drive or just about anything. Mine didn't do it all the time, but it did enough to concern me ... Especially since we were shopping for a camper. Sent from my SM-G892A using Tapatalk
  3. I recently had 2 cylinder's AFM system replaced. I've noticed in the couple months since that my mileage seems to have gone down a bit. It seems to go in to 4cyl mode just as often as before, but when it does many times the MPG gauge doesn't move. Other times it bounces back and forth between 18 and 24 like a clock ticking. It didn't used to behave like this. I'm driving the same roads. Also, (and I believe unrelated) I had the cat coverter y-pipe replaced under warranty a couple weeks ago. At least one core was rattling. I first noticed it after the AFM repair, but it might have been doing it before... I'm not sure. I'm just curious is anyone else noticed anything like that when there's was fixed.
  4. Mine used to creak a lot and rattle, too. Turned out to be one of my shocks up front was shot. Sent from my SM-G892A using Tapatalk
  5. Lol, I just realized this was my thread... So I guess you knew what I found. :-D Sent from my SM-G892A using Tapatalk
  6. I had pinging for years on 87 and I finally broke down and did some testing by running 89 for a few tanks and then 91. The 87 helped, but the 91 eliminated it. A friend also pointed out that the 89 may not be as fresh (in general) as the others since fewer people probably buy that vs the other two. I don't like paying for it, but it did stop the knock.

  7. Got the truck back yesterday. They said the screen and core of at least one cat we're loose and rattling. It was covered by the 8y/80kmile emissions warranty. Sent from my SM-G892A using Tapatalk
  8. Got the truck back yesterday. They said the screen and core of at least one cat we're loose and rattling. It was covered by the 8y/80kmile emissions warranty. I was told it'd be about a $2000 job (at the dealer) had I been past the warranty period. I had 78,500+ when I rolled in. The truck seems fine and the mysterious exhaust rattle that appeared after my AFM repair is gone. I thought it was a heat shield, but turned out to be this. Sent from my SM-G892A using Tapatalk
  9. I was told this afternoon that the converter has failed and will be replaced. There looks to be three on the diagram. I'm not sure if they mean all three or just one of them. It's going to be covered under the 80k emissions warranty. I got in just under the wire, thankfully. The truck has 78,500 miles. Sent from my SM-G892A using Tapatalk
  10. That sounds like a failing cat to me. I'd take it in or at least talk to them. I just took mine in today for a p420 code which is supposed to be a failed cat but the truck seems fine, no smells. We'll see what they say. Sent from my SM-G892A using Tapatalk
  11. Heh, I'd love to but it's my daily. My days of gutting cats and straight pipes went with my 5.0. ...God, I miss that car. Sent from my SM-G892A using Tapatalk
  12. Popped up driving down the highway on Thursday. Cleared it and it came back on Friday. Have ~78,500 miles and had afm failure about 4,000 miles ago. I feel like my mpgs have been down since that repair, but I have no real evidence. Taking the truck in Monday for them to do what they do for warranty claims. Should be covered by the federally mandated warranty on emissions equipment. Hopefully, they don't take a month again. Since the cat is likely bad, should I take the opportunity to run some crc cleaner for the valves? I wonder if I can sneak an exhaust past my wife on this one.... :-D Sent from my SM-G892A using Tapatalk
  13. Interesting. I was kicking myself the other day for not having them take pictures of my intake valves when they did my AFM lifter replacement a couple months ago. I'm pretty sure it's the cause of my (very slowly) increasingly rough idle.
  14. Got done installing all 4 today and took it on a short test drive. The driver side front shock was shot and passenger was close behind. After the work, the rattle is gone and it rides as well as I ever remember. The harshness I'd accumulated from the level kit, e-rated ko2s, and worn shocks is gone. We did put the extra spacer underneath and I'm happy so far. I'll report back if anything changes. Thanks all. I should have gotten these from the start. Sent from my SM-G892A using Tapatalk
