my replacement front O2 sensor will be here today. i'm hoping that it finally fixes these surging issues, otherwise it's something with the tune that needs touched up.
but i spent most of the weekend fixing this thing
replaced clutch master cylinder and clutch line
bled clutch
replaced from brake rotors and pads
replaced winter suspension/wheels/tires with summer suspension/wheels/tires
regreased rear sway bar, and stiffened up my rear sway (22mm bar, middle hole to stiff hole, effectively making it a 23mm rear bar)
going to be limping along this week. new summer setup isn't aligned yet, and my tires are shot to shit. but I have an appointment on the 19th to get new tires, alignment, and fender roll. so ruining already ruined tires isn't a huge concern lol.
