Hey all, new here but I've been looking all over and haven't found anyone having my exact problem. I just finished the 5speed swap into my 93 Subaru legacy. The car has been rwd swapped but that's not the important part RN. I'm having this super weird issue where it'll idle fine and drive okay for about 10-15 minutes depending if I'm driving conservative or if I'm getting on it. Then it will start to die. The idle gets super rough regardless of if I'm in gear or in neutral. The car is also in limp mode but I have no reason why as I took the car too the track after I finished it and it was fine. I've dumped a bunch into the car trying to solve my issue. New knock sensor, O2 sensor, cam and crank position sensors. Haven't replaced the mag but we know that it works and it's been cleaned. Any help would be great as this is my daily as well as my fun car.
