Okay, I have the APS cold air intake, APS bov, 3" APS downpipe back with cat-delete. A couple of time under hard acceleration in 4th (once in 5th) gear the car would start to run ruff or sputter and it felt like I was loosing power. Sometimes if I let of the gas and then hit it again its okay. I dont get a cel or anything and it happens at about 5500 to 6000 rpms (give or take). Any ideas?

 

no injectors? sounds like you either fouled plugs/running rich (if you have injectors) or have a sensor unplugged (but no cel so probably not)/blow off valve leaking badly?

No, no injectors. The bov seems solid but I will try to keep an eye on it. I wonder if a loose IC hose might cause this.......it only happens once and a while.
