Flashing check engine light

[AMDk7]

I just swing over to o'rileys and clear it with there scanner

The dude at autozone said their not allowed to clear the codes, never thought to just ask to use the OD.

at o'rileys if you are going out to use it in the lot they just take your ID and a Credit card and they give them back once you return the scanner

Just scanned my engine light and it also read p0300. Replacing the coil this afternoon. Hopefully I haven't damaged the cat.

Just replaced the coil pack. I am still experiencing hesitation and a occasional misfires. Do I need to replace the plugs and wires as well. I'm just wondering if there is anything else I should try. I am not getting an engine light but I can tell its not running properly.

Unfortunately misfire can be caused by many things. If you start hanging parts, you may spend quite a bit of $$ before the problem gets resolved. Best to diagnose first but OTOH, plugs and wires are basic maintenance, so depending on how many miles are on them, it might be a good thing to try next. If that doesn't work, you should get some systematic testing done.
