vin cod w-ok i changed the plugs, wires, coils, o2's and cats still has a missfire can someone tell me what am i missing pls??????

 

Capitals, periods, spelling.....

 

Any OBD2 codes?

 

haha your so funny ..... its the o2 codes coming up im changing them this week

 

so you say you changed them already and now your doing it again? Dont confuse o2 codes that are telling you something else is wrong IE dont shoot the messenger! What is the code? Missfires are not caused by bad o2's. Missfirs can ruin cats causing codes that are telling you the cats are junk..

 

Is that right?

Perhaps you took it the wrong way?

Iduno, -good luck man.

 

Please post the exact code NUMBERS.....................

 

Code 303 again I changed the o2 and three plugs the missfire went away for a bit then came back now I push on the pluv wires and it go's away for a bit I think its the new wires any suggestions?

 

Maybe the fuel injectors?

 

Did you use Motorcraft plugs and wires?

 

Yes I did. And I think the injectors are the issue everything accept #3 cyclender is firing on idle but give it gas and runs fine

 

Swap the injector with another if the miss move to the new location replace the injector. If it does not compression test.
