Spark Plug Replacement, 3 today, 3 tomorrow?

[Ruffrydasean]

I'm changing my platinums to iridiums, I just replaced the EGR gasket that was causing noise... seems it was never even bolted down >_> , Man was i ever in a rush putting on the S/C...

But.. my G/F needs to go to baltimore today in about an hour... I can change the front 3 no problem but the back three will be trouble.. should i just wait until tomorrow and do all 6... or will the diff. spark plugs cause problems??

Serious question...

I dont see why it would cause any potential problems but its recomennded to change all at once. if you change just 3 today, your car may idle a bit roughly. if i were you, i'd wait till there's enough time to do all 6.

yea... I guess i will.. just trying to save time i guess...
I gotta change them asap cuz the platinums seemed to have set off the knock sensors and a few other things need to be replaced now.. i just haven't posted it in the boards yet :/
the CEL came on.. and spit out a few codes
Mass Air Flow Sensor error
Air Flow Temp sensor error
Engine Oil Temp sensor error
and Knock Sensor...

At least tomorrow is labor day >_>
