clean your throttle body out with some carb cleaner and a tooth brush or something... and check your vacuum hoses on the throttle body, I'm in the process of replacing some hoses and gunna clean the throttle body, so i hope my issues are sorted aswell. (mine arnt tooooooooo bad tho) just want to keep on top of it really.

Sounds similar to the issues that I had, in the end I had to replace the AFM.  Try disconnecting it to see if it makes a difference....

I think he means Air Flow Meter... if not then check that too!

mine had a similar problem, it turned out to be the water temp sensor.

goodluck.
Wouldn't be fun if it was easy, but does it have to be this much fun?

Can you clean the MAF, if so what do you use and are there any gaskets?

Mass Flow meter, Air Flow Meter, Mass Air Flow, Air Consumption Meter...etc etc etc. All correct names for the same thing.
