Missfiring

Post by LayZieBoNeLBurNa »

i bought a mazda eunos 30x 1994 model
and it keeps missfiring i have tried servicing it new leads , plugs , fuel filter , air filter etc ....
i put in a o2 sensor because wen i got it the o2 sensor was dc at the front near the radiator so i replaced that

and it keeps missfiring
anyone know wat it might be?

But then again, after seeing your other topic about it not having an O2 sensor, yeah, I'd install that first. Then go from there.

Correct me if I'm wrong(I can be a little slow sometimes...brained my damage by drugging too many do's as a teen) but your car has the V6???
If so, could we bump to V6 Tech forum???

As for the missfiring...when does it do this?? In other words, at what RPM, at idle, or at speed???
My first check would be to see if the timing is off, considering that you said you have already replaced plugs, wires, etc...
