98’ s70 t5 manual/ car will not accelerate past 2.5k rpms
#21
Kinda weird that the O2 sensors caused the issue, especially without throwing a code, but hey, I'm glad it is running and great job sticking with it. Lots of folks would have said the hell with it.

Closed loop means it's running based on the O2 sensors. That is not possible on initial startup, and it my not even be desirable at WOT. If some sensors aren't believed, it may set a code and run based on a fuel table calculation. Some of the S70's will run with the MAF unplugged, and they run well, so evidently there is also a backup fuel table too.
It has some options for calculating how much fuel it decides to squirt in there.

Final update: Very ridiculous
Folks this is the final update! Thank you to everyone and all the help. I did a vaccum leak test today and found that the pipe connecting to the turbo (directly) would leak air AND sometimes wouldnt! I dont know how the car did not throw me codes! I did drive it HARD this monday and it drove fine! Then this wendsday it started to act up again, ALSO it still had no check engine light! I will be getting a new RIP kit and replace all piping! Again thank you to everyone!
