You might want to look at your O2 sensors, they can cause the motor to run lean or rich. also you might have an electrical issue that is tripping your ECM. your electronic control module might be faulty. best solution is to get a trouble code reader and find out what your on board computer has stored. from there you can repair and clear the codes.
