My 1990 nissan maxima has 210,000 miles on it. I just bought the car for a cheap price as a first car a few months ago. When I press the gas its slowly accelerating and then shooting up quick as hell ( up to almost up to 6 rpm) before shifting properly. When I shift my transmission is making a click noise that doesnt sound toogood but thats only sometimes not always. The hesitation and shooting off after putting my foot all the way to the floor and it not going then halling ass is what freaks me out. Im going to college 500 miles away next month and really need to quickly figure out how to fix this ; [ SOMEONE PLEASE HELP ME.
