Damn Check engine light wont go away after i installed a skunk2 test pipe. i tried the sparkplug non fouler trick but that didnt work and yes i tried using 2. I plan on getting some cams and intake manifold here soon, so i wana be able to tune it. What ecu should i get (i was told a p28) but idk? or should i send it to hondata and spend alot of $$$. The stock ecu is odb2 and its a 99 si. Thanks
