i have a 94 Acura Legend and and when i start it up iit rev's up and down but once i drive it it goes away? also when i'm in a light and the car is in drive it usually idle between 1000-1500rpm's and sort of feel like it's pulling the car. Does anyone know what the problem is?

 

You have a vaccum leak!

 

i just recently heard about the idle air control valve could that be another possibility or how will i know if i need another one of those. I hear that they are a common problem with honda and acura's.

 

call deal give vin number and see if it has ever been replaced!

 

Hello, Sounds like a bad fast idle valve. Make sure that your not low on coolant first. If your coolant is OK than replace the valve. I have tried to clean them & adjust them many times, no love. Just save yourself the trouble & replace the valve. Good Luck

 

thanks everyone i had a friend who had the same problem it was a high idle valve the guy turned the screw back all the way down and it stopped. He said thats a common problem that the honda's have and wants the adjusting screw loosen up it cause it to idle crazy but the screw can be turned back and problem solved.

 

Where is that screw located. I am having the similar problem.
