to the OP. you can decrease your gaps a little and it shouldnt hurt. i decreased mine by .006 or so with no issues. but that wont help you lean problem. do you have a wideband on your car? what the afr at ide? half throtle and WOT? |
Why would you want to know what his AFR is at idle and partial throttle?
Yeah, with the COP ignition, the practice of closing the gaps is not as necessary. Some manufacturers still recommend it and many old school builders / modders will still do it, but the stock Mustang ignition is quite strong.
