Whatz up rx8 family i have a 04 rx8 59,000 miles i bought from a dude about two months ago my queations are one sometimes when im at a ligjt and when i press on the gas it stalls a little bit doesnt do this all the time just a lil concerned second the driver was using syn 10w30 and i switched to 5w30 was that the right thing to do i will have more questions later im new to rotory engines so i would like to take care of this hot car

 

I also have a knn intake and my check engine light is on last reading i got was codes for cats misfiring any take on that

 

Actual code number would help.

First consider spark plug and coil change. It's a typical problem. You should also consider replacing the wires too at your mileage. It's quite conceivable that none of this has been done, even though it is something you should look at doing each 30,000 mile interval.

BHR also has an upgrade kit from stock. You can find it on their website http://www.blackhaloracing.com/produ...nition-upgrade. Little more pricey then just stock replacements, but definitely worth the extra $.

 

The coils look new so maybe i need to change the spark plugs

 

What kind of spark plugs should i purchase and where i live in the bronx nyc

 

Thanks for your reply

 

The K&N will give you problems like you mentioned.

It is a big noise maker, nothing more. Do a search. It is best to get rid of that piece of junk.

When you changed oil, did you go from Synthetic to regular oil?

 

I really dont remember ill have to go back and look what is the correct oil to use

 

Oem spark plugs.

 

You can't tell if a coil is failing by "looking at it". If one part of your ignition needs replacing, then it's likely that the rest need it as well, since one failure can cascade to additional ingition failures, and usually kill your cat as well. If the rest haven't failed yet, they are likely ABOUT to.

Just replace all 12 pieces: 4 coils, 4 wires, 4 plugs. You will be shocked at the improvement.
