I like the way you think Parker.. I like the way you think.

 

I'd also like to note that you're using the wrong spark plugs. NGK G-Power spark plugs are iridium spark plugs which is what the 400/430 takes. The 300 calls for twin ground electrode spark plugs.




The one on the left is what you're supposed to have. The one on the right is what you currently have.

 

Many people have reported that the single electrode works just fine if not better on 300

 

Oh well damn thanks for the info Parker.. Guess I should change my plugs then? Wonder if I can get any NGK XI's at AutoZone..

 

Do you mean NGK IX? Those are Iridium plugs too. I actually just installed those in my car.

 

Yeah NGK IX.. Hrm.. It's weird how they're not suppose to be for my car, but they're listed as useable on NGK.com and whatnot...

Do you think changing to the right ones will make a huge difference?

 

Truthfully, I don't know since I've never had to deal with this issue. I'm sure someone on here can fill you in though.

 

Hey D, does it seem like it boggs down on take off? We may can look at the injector seats, fuel pressure, pull those plugs and see if you have some mixture happening in the cylinders, basic stuff.
Also even though ngk pre-gaps they're plugs, you may wanna run the gapper and make sure they're correct.

 

try changing out your fuel filter

 

On the link i posted most the spark plugs offered for our vehicles are singles, im currently using iridiums as well. i dont think theres an issue? i just went by the chart provided below :\

I just go by what the manual says. When I looked there's a large "x" over the iridium plug on the GS300 section.

 

now you got me wondering if i put in the wrong plugs on my last tune up lol :\
i went with NGK's IFR6T-11
