Hey thanks alot i just pulled my plugs last night and was wondering what they meant.... looks like i am good though.

Did you read the "only valid if" part? Going out in the garage now and checking will let you know something, but the only way to accurately know what's going on while spraying via your spark plugs is to follow the procedure outlined on that page.

 

yeah i saw that but thanks

 

Cheap solution to the track side reading: I take an extra plug or two (more like all 8) and after I am on the return road, pull the plug to be checked. Normally I try for #7, since I used to run wet kits and 7 runs leaner than any other cylinder. Install the spare plug, hit the pits, inspect, clean and run again after any necessary adjustments. Good find Dave.

 

Good information. I have added this to the sticky at the top.

Great idea!

 

What does it mean when you have the plug tip come out the tail pipe as a glowing blob??

 

Means the tune up is good!! Geez and they let you be the nitrous director

Another question, whats it mean when your plug won't come out of the block.. Had that happen before.. Apparently the piston/valve took out a good chunk of the plug and it was stuck.

 

It means you need a bigger wrench and a large hammer

 

This is good info also.
