after a very long time its finally fixed, but anyways, once it was fixed and i started it, it idled pretty high so i adjusted it and made it right, but when i hold in the gas just a little bit it goes... vroom...vroom...vroom as if i was revving it slightly. do you know why it would be doing that? my grandpa is extremely good with vehicles and said its probably because its old and it might not idle perfect because of its age(its an 86) it only has 80thousand original miles so i dont think it could be of high mileage since it doesnt have high miles. any suggestions would help. and the water pump was off so it didnt have water/antifreeze and when i turn on the car the "add antifreeze" light comes on for a little bit, does that just mean its not full or what?

 

woops. my bad. i put this in the wrong section. sorry
