NTK sensors???
They're made by ngk, pretty good company, any experience with these sensors??

 

WELL. Brand new wires installed wednesday, not until breaking off athreaded barb on the pass side of the intake manifold and dropping a piece of it into the plenum[:@][:@]!!!

After everything was done, truck ran great, until I drove about 5 miles. Same old rough idle (not stumbling, just a little extra vibration). Erased codes, and drove some more. Checked and erased the codes today, and all the same codes, with an additional cyl 6 misfire..

Found new o2 sensors, and they'll be here in a week or so. But, as for the misfire, i'm thinking possibly coil? Any ideas??

 

not to be random, but im a novice at this stuff, can i buy a code reader at advance or auto zone?

 

Yeah, I got mine from one of those.

 

I wouldn't jump into a coil yet. Get the 02s in and reset the codes. I am still iffy on your plug wires, time will tell.
In the mean time, if you can keep your driving down till you get this handled, you may be able to save you cats.
Let us know how it goes.

 

Finally got the o2 sensorsinstalled today... I didn't drive it much, but the idle seems smooth, and no codes yet...

Keeping my fingers crossed...

Thanks for all the help
