Check all the tubing on your intake manifold, make sure they're not leaking air.. You can usually hear it, but a specific noise in the engine bay when you lift the hood, and rev the engine.. or even in idle... I can't explain the noise, but it's the noise of sucking.... sorry I can't really help much more than that..

what do you mean check for air leak? and how?
Thanks.


You gotta change O2 sensor every 50k, if it hasn't been done, smart to do so... If it's a rough idle, i'd check for an air leak.. and when was the last time you changed your air filter?

recently, i seem to have lost a little power and have occasional rought idle in park..i have 125k, should i suspect the o2 sensor? to my knowledge it is original..
