changed my plugs today and it ran real rough for about thirty seconds then smoothed out. not concerned just wondering why it ran rough after the initial start up. and by the way i love how easy it is to change plugs in a straight six.

 

Did you disconnect the battery when you changed the plugs?

 

nope

 

Then I don't know.

 

one thing that i didn't mention was the back plug wasnt even tight. i probably could have removed it with my fingers and the extension. maby that had something to do with it.

 

Was it that loose WHILE it was running? If so thats why it was running so rough.

 

Straight six? My rear plug is always loose.

 

Maybe engine just had to get used to the new plugs or the engine was just cranky for putting in something new. But seriously, there might have been some residue or something on the electrodes until it burnt off.

 

Yeah a friend just told me that his straight six rear plug is always loose. I gotta check mine this weekend then.
