I think you should visit crappy before they close and get a proper spark plug.

NGK TR55 because they're cheap.

Do you see blue smoke on startup?

I know it's been kinda cold lately, so a lot of condensation will be expected.

How old are the wires?

Check for continuity from the O2 sensor connecter to the PCM. If they check out, you likely need a new sensor. Alternatively the PCM is dead or dying.

you would'nt push what scrapping the motor cause i dont think its going to need that i put proper tr55 in there and same outcome on just that 1 cyl
white smoke out the back but that just the oil in the chamber for the test no blue smoke only white coming out. if the pcm was dead i think id get more codes then just the 02 one but thanks for helping matt.

this cars got a mint body on it so i wanna keep this powerplant if possible so iam going to take it to a shop tomorrow and get then to yank of the front heads and have a look at that 1cyl from top and bottom just everything iam thinking point towards the head. and that was not touched when the cyl was replaced the first time time so maybe the mechanic never got a good look at the head before he put it back on.
