ok so i ran into another problem. i went to get my emissions done to get new plates and they cant read the tests cause my ecu wont work. it read only one out of the seven tests. i unplugged my battery for the night. about 9 hours and my check engine light wont come back on and my ecu just wont work. i drove it about 600 miles now and its still not working. any ideas of what i should do to fix this??????
