Message Hi guys,
My Z has had some minor idle issues (see thread below), but now it started running rough at idle. My coil pack connectors are shot, so I'll be ordering more (unfortunately, one of the coil pack clips on the coil pack itself is also broken, but I'll worry about that later). Anyways, in my quest to help my Z, I pulled a spark plug to check on it and see what kind it was. It is an NGK BKR5EGP. Now NGK's site says this is one of the plugs for the Z (mine is a 1990 N/A), but most places I read to used the PFR6G-11. Are the plugs in my car good, or do you still recommend the PFR6G-11 plugs (I searched here but found only 2 hits)? Also, a pic is below. Do the plugs look okay? Thanks much!
