When I'm driving, the car will randomly lose power and the RPM will drop really low and stall.
For example, I'm driving normally and the RPM is at 3000. Next thing you know, it goes from 3000 rpm to 500.
This is when I usually shift it into neutral and give it lots of gas until it revs back up again.
Of course I can't reliably drive the car if this happens every couple minutes or so.
It'll start back up no problems if it does manage to stall.
I recently swapped a rebuilt 5sp tranny in there. It shifts smoothly and all gears work fine.
Also tried to check if the ECU is throwing any codes but I don't get any blinks at all.
Any advice is appreciated. Thanks!
