Rep Power: 0

Hey I have a p032 code that pops my cel . When I'm driving and give it full throttle at around 80 mph the car stutters and won't accellerate or rev any higher and that's when the cel comes on. As far ax mods go I have an aem sri megan header and test pipe and apex'i ws2 catback I replaced both 02 sensors and alternater and battery about a month ago when I did the exhaust I have had no issues until a few days ago. Any help would be appreciated.

Check your knock sensor.

Knock sensor is kinda above the oil filter. You can go from the bottom or take the intake off and go from the top. Either way it tends to be a PITA. It has a 3 terminal connector.
