i swapped the stock turbo for a 22t with a wrx turbo, and ever since i did this when i drive on the highway for about 3 miles the check engine light will come on. Also after the car has been running for aprox. an hour it will shut off when i come to a stop sign or a stop in general, any suggestions on what i should check? im writing this from school so its all i have off the top of my head let me know if you need more detail. thanks
