I have an 06 evo 9 with light bolt ons that I bought about 3 monthes ago, it has been running fine but it has started miss firing at WOT rite around full boost the car runs fine just driving normal. when it first started it would do it all the time now it seems to do do it about 50 percent of the time i changed the plugs so i know it cant be fouled plugs. any help is greatly appreciated thank you

 

Do you have a deleted cat?

 

yes

 

Did you make sure all 4 spark plugs are properly sparking? Or did you just change plugs?

 

Which plugs did you get? You need to check their gap.

 

i did only change the plugs and i used factory plugs gaped to.023

 

Im in hershey If you want I can give you a hand with it...... could be a plug wire, or coil pack. Plug wire is pretty common because you have to be carefull and only pull on the rubber boot when you remove them, found that one out the hard way.

I am located in hershey right off of 283 and I have two evos, so we can swap some parts to see if that fixes the problem

 

I appreciate everyones help, I changed the wires and it has stopped so I guess that was the problem even though there was no visible dammage to them. Thanks

 

Nice to hear that! See the forums do pay off
