Need Help

I have been battling code p0306 for the past few days. I went to buy some lucas tune up in a bottle, and the next day the CEL went off. But when I do the key click the code still remains. Should I just do a reset and hope for the best? or change the plugs as well?

Did you listen to any off us?? What's that stuff in a bottle your talking about?

U have a misfire. What have you done?

Plugs?

Coil rail?

Even 02's were mentioned in another thread of yours.

Resetting the light will shut it off (temporarily) but it will come back on when your computer re scans the system.

Yea but what I'm saying is, it went off on it's own. I didn't reset. Yesterday it did misfire a little when we looked at it, but it seems to run way better after the treatment. I did pull a plug and it did look like shit, so
I'm gonna see if that makes an improvement when I swap
Em tomorrow.

Make sure you put the correct plugs in. OEM if possible. None of that Bosch crap.
