Hey guys, I have a 93 n/a supra and haven't had any problems with it until now. Car shakes in first gear pretty bad and doesn't want to shift into second, exhaust is significantly louder and makes a popping noise. The weird thing is it only does this in the mornings and not later in the day. I live in Fl so its warm in the mornings so the car is definitely warm. Has had all maintenance and has 97k miles. Any response would help. Thanks!
