Hi all,

I am new guy in this forum. I have a issue and need help.
OK, first of all, my car is 2003 Saturn Vue I4, 5 speed manual tranny, 92xxx miles on it. I just replaced 2 oxygen sensors ( one for each upper and down tream ), 4 new NGK spark plugs , new K&N air filter. Car run and drive fine but only one thing happen last week that engine is running little high Idle at 1200 RPM whenever I am in the red-light with neutral speed or depressing clutch or it's at parking. It used to be at 700-750 RPM.

I don't feel good when it's at high idle. Anyone has ideas to help me out. Thanks a lot.

 

Just let everybody know that I fixed it by replacing Temp air flow sensor. After I make sure all vacuum suppose to be good in the spec no leak

 

It's always a pleasure to see a contributor think their problem through, and come up with the solution that puts them back on the street -- congratulations.
