Fuel Additive

[Philster]

My 1994 gas D90 had trouble passing emissions and is running a little rough. Im thinking a fuel additive might help. Does anyone have a recomendation? Thanks for looking.

I use the Lucas brand fuel additive.

When did it start to run rough?
Does it run rough all the time, only when cold?

Could be many things, here is a list:
-may need a tune up, plugs wires, rotor/cap
-stepper motor, will affect idle
-O2 sensors

Fuel additive can't hurt, but I'd look into other areas...

Good luck...
