Ive searched all over but cant find my answer. i have a obd1 gsr swap into my 89 4dr. i just finished the swap and had been driving for a week when i was headin down the road and it just started bogging hard and thew check engine light. So i pull over. when i start the car it. idles really rough then goes to limp mode and throw map sensor code. i tried plugging into the othwe map sensor still on my fire wall and it does the same thing. When i press the throttle it boggs out right away. doesnt even make it to 2k rpm. and ideas?
