Well how about replacing it? Then we'll all know for sure I guess.

 

Well I was gonna do that...but now today Ive drove 80+ miles&no code has came back on&it hasnt don itso...idk???

 

I have a rebuilt transmission with like 200 miles on it... and a misfire issue that when the torque converter locks up causes the whole truck to shudder violently like its gonna shake itself apart... when I hit the overdrive button I know its working because I can see my rpms then jump back up and then the shaking almost completly goes away.... you might want to try doing the same thing to troubleshoot whether is a misfire or a transmission issue... trnasmission error codes do not turn the check engine light on and misfires do not always throw codes so...

 

Question...I took the ore cat 02 sensor off&when I did I heard a woosh or pop like it was air tight maybe? Thoughts?

 

clogged cat?

 

Thats what Im guessing,I pulled #8 plug&it had more build up on it than others.
&the guy I got it from said the plugs &wires not too long ago but from what I see it dosnt look like it.So Im gonna swap everything out.Cap ,rotor,wires...but I noticed on some of my plug wires those suckers wont come off no matter how hard I pull

 

Get a pair of plug wire pliers. Twist the boot to get 'em to break loose, and then pull. Works every time, and doesn't trash wires.

 

yup!....

 

Just bought new plugs&wires&the plug tool.Gonna put em in tomorrow &gut the cat.Quick question if I clear the codes how long does it take to throw em again like 30?

 

Codes can come up in any time frame. There is no set time.
