ok so i lost my license in december, and my car has been sitting in the garage since then. i start it every monday and every friday and let the turbo timer go for 9 min and 30 sec...but while its been sitting there i put in spark plugs and cables. and i took it out for a go around the block, and it sputters after about 4000 rpms with full throttle....is it the spark plugs or is it cuz its been sitting there too long?????

 

Why new Cables? That might be your problem, I would put the stock back on and see if that's it. Also, what gap are you running on the new plugs?

 

What new plugs did you put in it?

 

it could be bad gas did you put a gas stablizer in it when you stored it?

 

What about a boost leak? I know when I popped my TB hose it ran like crap.

 

yeah i bought the magnecor cometitioN cables and the iridium ix plugs and the guy said i didnt have to gap em, and the gas may be right totally forgot about that

 

i do havea boost leak but its never been like this before...and i have had the leak since for like 3 monthes before i lost my license

 

for me, my car sputtered even when i put new spark plugs in, i used the ngk br7es copper. i think my problem is maybe i didn't gap it right?

 

Which Iridum plugs did you put in? Brand/Model

The only reason I am asking is because its possible you got evo8 plugs, which are different than your evo9.

 

well heres a picture of the box

i dunno what else...there is like code on it its...LFR7AIX

 

and yeah the guy i talked to when i bought em said i dont have to gap them

 

Call me crazy, but after two different cross references....

LFR7AIX is a subaru plug.

The site shows the LFR6AIX, with the 7aix being one stage colder.

 

one stage colder?

 

This is probably stuff for the tech section, not to mention the brainpower that posts there is a bit higher...

But in short,

Spark plugs often come in heat stages. In the model you posted, 6 and 7... with the 7 being one stage colder.

If you were making good power and your plugs were burning too hot it would burn the fuel too quickly causing your A/F ratio to be off. One stage colder would just increase the temp of the plug so it would not get as hot under the same conditions.

Although I have read no set in stone data on which plug range to use on an IX, I have been told 1 stage colder for every 100hp over stock.

Nether the less, the bigger issue would be the wrong plug in your car if infact that is the model.

(i think)

 

oh wow....learn something new every day....did u happen to see the recommended plug to get for the IX
