Car Needs Attention > What Should I Be Doing?

[WOG BOY]

Ok here is the scenario....

my car wont idle constant, it will vary up and down each and every time that i start it up. It wont be the same rpm twice. Also after a quick acceleration, when i take my foot straight off the accelerator the car rpm drops right down to almost 0 just before the point of it stalling (it has stalled a couple of times).

Also i cant hit 7psi on boost either....no matter how hard i plant the foot, it wont go over 5psi...and the rpm does go over the 4.5k mark as set via the boost solonoid....

also, my fuel economy is possibly the worst in any car ever.....i drove 244km's of hi-way driving (steady constant 100km'h) and it cost me $40....that is hugely uneconomical....u dont wanna know what i get around town, but use that as an idea...

The car is completely stock so i cant see the issue being upgrades....

So what should i be doin? taking it to get serviced fully and properly? or does it sound like it needs that and then a proper tune?

also i dont really trust anyone with my car round here so where should i take it if i can get it to Brisbane or something like that....

plz help me here as my pocket is suffering heavily as u can probably see!

it could be a leaking bov, or a crank angle sensor issue, or many other things, but start there. also check your spark plugs.
