1995 impreza coupe ej22t 2.5dohc swap, Robtuned, brembos. Sti seats and sti go fast goodies
Hi, need some help if possible. My impreza is almost finished but I have a few kinks left and it's stumping me. We did a ej22t swap into the impreza using the engine harness and jdm wrx ecu from my 94 wagon due to bad rust on it. I made sure the wagon was running great before swap (I did no upgrades or changed anything during swap) so I could rule out issues and it was running fine. It runs great but about every 5-10 min the engine will just die, doesn't matter whether I'm applying gas or at a stop. I just turn key off and it starts right back up no problem and is fine for another 5-10 min (it did not do this in the wagon). I have changed main relay, fuel pump relay, swapped maf and got a new Robtune but it's not acting like fuel issue but electrical. It's like I turned the key to the off position. Any ideas of where to start looking???
