I just installed a cone filter, coupling to MAS Short bend for hood clearance to cone filter tuned to inside bottom of OEM box. I did that for lower noise and keep A/C lines safe. Fender side of box is cut for air flow. All clamps tight.
Now, at between 1500 and 2000 rpms the engine has a smat sputter. Even a low grade bucking. This only happens when going up an incline or hill. I test drove it about 6 times. The CEL came on on the third but reset when I disconnected the neg. battery terminal then reconnected. It got a little better after reset but is still there. Car runs like a "bat out of hell" the rest of the time. VERY noticable hp change. This was done using the ASS DYNO method. Torque improvement as well.
PLEASE HELP
