plug gap ?
heres the deal .ive always ran my plugs at .35 and a couple weeks ago i changed to .32.i saw alot of people saying f/i went .32 so i tried it.trucks been running ok but not impressive for 10 psi.my idle was set at 750 so this week i had allen set it at 650 it drove the same as usual for 2 days.now when i start up after about a minute when the idle comes down its skipping .no its not the cam .thats a diff skip.this is a hit and miss skip that seems to do it at normal driving going down the rd also.just everynow and then at cruising i feel alittle hicup also.most noticibly at just lightly pushing the pedal skip skip skip go.so my question is will the plug gap cause this change.?maybe by lowering idle fouled a plug.thanks ahead.
