running like crap...

[91_SHOster]

So I seem to have this problem with my 91 SHO. it has a terrible rough idle when started after driving it around and parking it. It seems to be running a little rich and just hiccups untill you give it a little gas, but day after day it keeps getting worse. I plan on changing the spark plugs in a day or two hoping that maybe a plug isn't firing and it's causing the rough idle, but if i'm wrong i don't know what could it be
any help would be great

thanks-Andrew

Codes will help us help you, check the link in my sig. Also look for oil in the plug wells that will be a sign your in need of a upper 60K.

is there any way I could check for codes without a scanner? i've seen people use paperclips to check for codes....

Wow I donno how I read that, but no its not good enough because the oil will come back. Its going to require a valve cover and plug well seal set. And most likely the oil has damaged the plug wires too.
