this light comes on after running for approx. 8-10 mins. if you shut car off it takes that long to come back on. i jumped the box where you check the codes down under dash sort of in the middle by the hump. the codes flased out 12, 15, 34, and 43. one is map sensor took it out had it checked its ok. the other codes refer to the esc unit. i have no idea what it is. any help for this problem on my "89" brougham.
