If you type this question into google you will get several equivalents. You may find questions like this are more quickly answered using google rather than waiting for Fixya answers

bosh and ngk are better option

Throw away the auto liters and get yourself four champion spark plugs. Champions work in chryslers, auto lites/motorcraft work in fords, NGk for Japanese, ac delco for GM's, Bosch for European.

Follow ow those rules and you will likely never have a drivability issue caused buy the wrong spark plug.

Set them to .035" and you should be good to go.

Try putting some Injector Cleaner (from the auto parts store or gas station) into your fuel tank to see if that helps with the rough running. Follow the instructions on the bottle.
