93 cutlass supreme severe prob!!!!!!!!
the other day when a was driving some a$$hole was following really close and it made me mad, so i accelerated away from him and the next thing i know hes right on my a$$ agian, so this time i accelerate and change lanes into a turning lane since i was turning anyway. well sure enough the jerk almost hits me, when the light turn green i tried to take off really fast and he speed up and swerved in front of me. so now im really mad and i really got on it this time, i get around him and turn into a grocery store parking lot, the next thing i know the car has a blueish white smoke that smells like fuel and has a severe loss in power. so i asked my good friend who is a gm tranny tech and the only things he could think of was a coil pack failed, or a sparkplug got some carbon in it and/or failed. also the egr gasket leak the same blueish white smoke when reving the motor. i have tested the coil packs and there all good, and i have changed all the sparkplugs and wires and still no change, SOMEONE PLEASE HELP THIS IS MY ONLY CAR.
225,000 MILES, 3.1 LITER ,ON THE CAR , NO ENGINE LIGHT OR CODES THANKS

Re: 93 cutlass supreme severe prob!!!!!!!!
There is no way to diagnose this from here, could be many things, blue is oil, something may have failed in the engine itself, this needs on site diagnosis. Check for a stuck pcv maybe?

Re: 93 cutlass supreme severe prob!!!!!!!!
well when u rev the motor it puts out black smoke, almost like its running rich, also if something in the motor failed it should put out a knock sensor code or something right?

Re: 93 cutlass supreme severe prob!!!!!!!!
well the fuel pump was replaced about a week ago along with a new filter, so mabey the fuel pump regulator might be stuck open, since it might have been broken before the fuel pump change but went unoticed because of the weak pump, ???????
oh and there is no knocking,
