Here is the plug from bank 1. The car is on a heads and cam tune. I sprayed 50 down the line. Before the pull I installed new BRE7F, let the car idle for about 10 minutes to bring it to 170*, made about a, 1/8 mile pull and immediately cut it off and pulled the #1 plug. There was no timing pulled. Where do I go from here with tuning my car?

From what I have read,

you do not want to idle on the plug
you may want to check 7 & 8 plug as they are hotter.


Some good info to read while someone more knowledable responds

Thanks, this is all a learning curve for me. Hopefully a successful one.

Hey Trey,

See how the color is up around the top of the porcelain? That is from all the idling. You can not get a good plug read after letting the plug run for 10 min. We need a fresh plug, burnout, pass, shut it down. Otherwise we might be going off the tuneup at idle or part throttle.

Get us a clean read and we will help get you lined out.

Ok cool, the mallory box will be in tomorrow. I'll put it in, fresh plugs, pull 2° and post pics.

Good deal.
