  1. Going going gone! Sold my S550 GT

    Most definitely. My dad had one before I was born and both of my parents said they wish he kept it. Sold it because he needed a truck for the winters
  2. Going going gone! Sold my S550 GT

    After a year of ownership, I've officially sold my s550 gt. It was a fun car and it was an awesome car I planned to keep for years to come but issue after issue just arose to where I didn't see it viable to pay out of pocket for repairs. It was a 2019 and it had 2800 miles when I bought it...
  3. Has oil weight change for Coyote Gen 3?

    I have a 2019 as well. I would get motorcraft 5w-20 full synthetic my first year of owning my car. It was definitely noisier throughout the engine with it. Ever since I had TSB 19-2140 dealt with and my mechanic adding 8 instead of 10 qts of oil, I switched to motorcraft 5w-30 synthetic oil...
  4. Air-Fuel Ratios for Stock & FP Tune Cars

    Question about AFR, I know it's an old thread, just trying to get more understanding. My car idles at that normal range but when I was driving home yesterday evening from work, I noticed it would be at 12.3-12.6 when I was slowing down and just stopping then after a few seconds it would go back...
  5. Winter = 💩

    Can't wait for it to get nice and take my ride up to Wisconsin for camping.
  6. Engine knock 2019 GT with Ford tune, no codes.

    Perfect. I noticed it when it was cold about an hour ago but once engine was warmed up it went away.
  7. Engine knock 2019 GT with Ford tune, no codes.

    does your car still make this noise? I see in the post above you removed the performance tune and knock went away, but how has it been since last post? Any new mods, any new tunes, etc?
  8. Idle thumping/knocking

    I'm all stock. I plan on getting 47lb injectors at some point for an e85 tune.
  9. Idle thumping/knocking

    Perfect reply, thank you so much for this. I wasn't losing sleep, but just want some ears on if it's a characteristic. It took me a minute to come to terms with the others but this engine is a beast under some good load. 👍
  10. Idle thumping/knocking

    Alright here's a few others that have had same issue: https://www.mustang6g.com/forums/threads/another-gen-3-coyote-knocking.207034/ Here's just 2 sources. I saw another that seemed similar but videos were gone.
  11. Idle thumping/knocking

    if you wear ear buds or headphones you should be able to hear it better. There's another video on this forum of the noise. My car is acting kinda wonky recently and this is one of the things I've noticed. I'll get more data and videos tomorrow. I'll also repost the video I'm talking about from...
  12. Idle thumping/knocking

    I've seen threads beforehand and I know that some people say it's normal, some don't know. I just need honest opinions and real cold hard truth from s550 owners. I'm coming to terms that these engines makes loads of noises as I've made other threads. I just want to know actual info on why or...
  13. My engine might be shot because of timing chain issue

    No no I'm just curious as to what would be the indicators to find something out like this. I know CEL and codes would show just other indicators.
  14. My engine might be shot because of timing chain issue

    Is there any way to know If it indeed jumped a tooth?
  15. Winter = 💩

    Don't forget the 1-2" of snow tomorrow then mid to high 60s starting Monday. Gotta love chicago weather.
  16. Steeda Q850 '25 vs GT350 '25

    I've heard of steeda bits and pieces, but man they seem like such a great company with the research I've done. I think the q850 is cooler and probably a better bang for your buck.
  17. 5w30 engine oil swap now engine making noise

    It's what I'm best at 😂😎 Nah I'm trying to learn as much as I can with this generation I can. Every little tweak and parts purpose.
  18. 5w30 engine oil swap now engine making noise

    So far though 5w30 has been a great decision. You think my VVTs will go out with continued use?
  19. 5w30 engine oil swap now engine making noise

    I've seen plenty of messages of people using it even without finding the tick. They do it as an extra precaution.
  20. 5w30 engine oil swap now engine making noise

    It makes sense. My mustang sounds like a diesel sometimes in the cold. Ever since I switched it to 5w30 it's been smooth.
