My dad just bought a wrx for himself. Its a 2006 and has about 73k on it. He was told it has some mods by the previous owner but it doesnt seem like anything crazy (Im not that familar with these cars). I do see a sti intercooler, boost gauge, straight piped. When we start to give it 75% throttle the check engine light flashes? Anyone have this problem before? If anyone could help that would be greatly appreciated.
Thanks in advance.
