1990 750 smoke + EML need help

I just bought this used ran good for half a day then EML light came on, seems to lose power and has lots of white smoke periodically Put low grade gas suspect that might be problem. check engine comes on occasionally when low idle.


Just an FYI to this put in the injector cleaners, octane boosters etc,, topped of car with high octane gas seems to be much better now. Check engine light still flutter on occasion. Seems Shell and BP gas work the best.

I did find a good link relating to EML and cleaning the throttle something or others.
