s13 speedo question
so, i have an 90 hatch, close to 170k. the speedomoter stays at 35-45 constantly. sometimes itll fall to 35 and slowly rise to 45 while accelerating, at any speed. is this most likely caused by the speed sensor? or should i rip the cluster out and see if the motor behind it is going bad?
oh and when i got the car the gas gauge was around 1/4, started driving it and it fell to empty and has been stuck there. bad cluster also? any help is good help. thanks
