Starts no issues every time runs a few minutes then runs lumpy smoking which is blueish comes and goes same as when under pressure but when driving the battery light goes out when under pressure comes back on when Idling . Help would be appreciated :brickwall:

Have you checked the alternator?

The battery light going out when under load points to an alternator not producing enough output.

Does the eml stay on when the car is running?
