I recently rebuilt this EJ25D engine. Everything was a success as it will turn over easily. As soon as I turn the key however, the car builds to 4000 RPM within the span of 2-5 seconds. I tried adjusting IAC, even unplugging it. No difference. I tried the MAF, unplugging it just made it run down...

Hi all, I recently noticed that my seat belt chime has changed pitch and not in a good way. Does anyone know why this might happen or how to remedy the issue? The car is an 08 Outback with 96k miles. thank you
