2006 gt self revving when cold?
I just bought my 2006 gt 5 speed about a week ago. I have noticed one thing when i start it up to go to work in the morning. If i just let it sit until it warms up it is totally normal and fine but it i try to drive it cold i notice that when ever i stop, the car revs it self up. it bounces the needle from about 750rpm to 2000 or even about 2500. I have been doing a little research and ive found that some cars have the computer set so the car will try to warm itself up but my gt is bouncing the needle about once every couple of seconds. it seems like it would be bad to rev an engine like that when its that cold in the morning. Also it is only revving itself when it is in neutral, clutch in or out. once i put it in gear or drop the clutch a little it seems to level out. Is this a problem or does it do that on purpose? Has anyone else noticed this? ive heard it might be something called surging, the engine trying to warm itself up? Also ive been told to clean my throttle body, how would i go about doing that? is there a spray? just unhook the intake? or do i need to take the whole thing off?
