CEL p0456 on 2013 n/a help!
I have a 2013 FRS manual n/a with 50k miles. Stock except for gruppe s cattless header, mxp comp rs exhaust, and oft stage 2 tune(mods have been on for a year with no problem till now)
Just had the p0456 cel pop up for evap system. Tried doing some research and people say the gas cap but mine is tight. I cleared the code to see if it will come back on but as I've been driving it doesn't seem quite as quick as usual, has hesitation when first pushing gas pedal, and runs rough in reverse slow speed.
Any help or tips would be great, I tried looking for loose vacuum lines but can't find where evap system is.
