any free way to clear pcm of codes

got a gremlin that is coming and going with my car p0358 which has been going on for sometime even with the previous owner, i did not know this until it did it for me.. i am trying different fixes and i have it narrowed down, is there a way to clear the ses light/pcm without a scanner tool, possibly disconnect battery or somthing along them lines, that way i am able to try somthing and drive it to see if it comes back or not.. thanks

i am aware the code is ign misfire cyl 8, i ruled out the coil allready, im trying ign coil harness next or maybe try and ign coil relay(previous owner said that is what fixed it for him) im a real noob with ls1's (came over from team blue oval)

thanks guys

Another Noob Question...

From my reading if you unhook the battery any codes set will clear - OK. Does the computer have to go through a relearn process at all once you hook the battery back up? As mention above the tune is not affected but nothing goes away?

Thanks

It does. Just start the car. It will have a rough idle for a minute or two and it will smooth out and you all set. Your tune is in the flash memory so it wont go anywhere or change at all.
