Why does my car lose power and stop past 3k RPM?
The engine loses power and refuses to climb past 3,000 RPM at partial throttle, even though there are no warning lights or limp mode indications. This sudden restriction prevents the car from maintaining highway speeds, forcing drivers to constantly slow down and crawl until the issue temporarily calms down.

“I’ll be driving roughly 70mph it’ll do fine. But as I was going home (around 70mph) it started losing power, I could slow down to 60, and it would do fine, then it would lose more power. Id have to gradually repeat that until I was at 40mph then it would calm down and I could speed up”source ↗
“havent scanned it but when i was driving it in the morning it wasnt like that, like the car ran super good. and then when i was driving home tonight that happened”source ↗

“when i was driving it in the morning it easily went pass 3k rpm with the same throttle, and the rpms didnt climb that slowly”source ↗
