hi, i have a mazda 626 few months ago i had a busted engine wiring after sending it to a mechanic the problem was fixed but gave me a new one.. my idle rpm at times rises from 800- 1800 on idle occasional but getting frequent this last week. also air intake is quite noisy think adjustments are not properly set. could you help me on it..

 

What year is it? I know the '98 and later models don't have adjustable idle RPM, but earlier versions do.

 

hi tnx, sorry im not so sure but i think its a 1997 version , a friend told me bout a servo... not sure what it means...
