you'll know if it's wrong. won't run right. if the car runs ok, don't sweat it.

 

you mean if it starts misfiring and such?

 

misfire, sputter, hard to start, choppy idle. things like that.

 

cool thanks

 

yep i missed the 0 aswell... sry i blew up. .032 it is

 

pimp dawg dizzle

 

You guys are talking about 38? 32? According to my Haynes Manual it says 42 or 40 depending on your engine, year ect...
I have one step colder plugs gapped at 40 instead of 42 as reccomended by the company that did my tune.

 

that's for a stock setup though.

 

ok gotcha thanks

 

The idea is always to have the largest gap possible without getting spark blowout. For a 2.85 pulley I would start at .034 and work my way down from there if you are having problems.

 

will you stop pointing out the obvious Mr. Belevedere? Ya would think none of us have the complete set of workshop manuals for Cobalt and just stick the stuff on our cars and hope for the best....
