Why does my 2001 Honda Civic keep overheating?
Ok so I'm having many problematic symptoms with my 01 Honda Civic. 1st thing is that my check engine light is on, it's been on for about 8 months now, the code says that it is my vehicle speed sensor, when I took it to the shop they said the the speed sensors were fine and that they're putting out the correct ohms, they suspect it could be a wiring problem, what are your thoughts on that? 2nd my car likes to fluctuate between 2000 and 3000 rpm when I first start to drive but goes away for a little bit, often times when I'm sitting at idle the car once again fluctuates between 1000 and 0 rpm when it hits 0 rpm the car shakes uncontrollably, sometimes my engine would just shut off, suspect it could be a vacuum leak i don't know. 3rd problem, even when I fill the radiator and reserve with coolant, it still overheats after long drives, maybe 45 min or more of highway driving then when I get off it starts to overheat. It never overheats when I go to work which is about 10-15 min away. When ever I open my radiator cap and reserve the next day after it overheats there's hardly anything in there, anyone know why this is happening? How much would it cost to hey all of this fixed?
