Thanks Disco MIke. I have already cleared the codes, so I will go get them read again. Anybody know where to get some inexpensive o2 sensors.lol I'll get back to you guys later. Thanks for all the help!

 

I changed the front 2 o2 sensors, felt a little better but still missing. going to change the back 2 tomorrow. Then I'll get the codes cleared and see what happens. They had put denso plugs in and the #2 cylinder was ashy white at the tip. No moisture and Im all plugged up so I cant smell anything.

 

Could be coolant getting into the cylinder which caused the issue with oxygen sensor. Possible head gasket. put a new spark plug on it and let it run and see if it goes away or not. Forget the plugs and wires its important to solve the one cylinder problem. also add dye to the coolant. I want to know if the coolant is getting into it.
if the wire doesn't fix the intermittent issue then swap out the coils to see if goes away. if its the coil then it will be on another cylinder. If it doesn't go away then its internal. mostly likely the head gasket.

 

Wouldn't the plug be wet if coolant is getting in? I dont see any coolant anywhere. Ill check tomorrow though. You don't think a bad o2 or knock sensor would be the culprit?

 

Send me your number if you want some help.
