got car out, driving car and brakes decides to work without me pushing the pedal, get put back at the shop, sits, goes out again, this time the same thing happens but i decided to continue driving, like a dumbass, car starts to over heat, i pull over, shut off car, try to start car, car wont start, gets towed back to shop, sits for a year, swap the motor to a newer shell, sits some more, replace ecu, ignitor chip, CAS, and bought a brand new sr harness. car starts up and goes home. all of the old fluids was drained and refilled by the time i took it home. and it's been acting like that ever since
