problem worthy of lols...

The bit that i don't understand is you are saying it's so easy, then you are saying you can't figure out what is wrong with your car?

When i'm stuck on something i don't know much about, i ask someone in the industry. That usually follows with me paying them an agreed fee and them fixing it for me.

But hey, i'm no expert either.

Start the engine and spray aerostart around the manifold. If your RPM rises, you have a vacuum leak somewhere. That's fairly easy to determine.

There you go! I just learnt something too

Hope it sorts out Mick, unfortunately I don't have anything constructive to add to this thread though!

What's so hard to figure out? I installed a new manifold, which wasn't physically hard for me to change as I know how to unbolt and bolt a manifold onto my vr6 engine. Like I previously said - the problem I have is with stalling, and I don't know why it's happening or what it has or has not got to do with my new manifold, which is why I asked about the problem on here.

The manifold came bolted together with things like the throttle body, ISV, vacuum lines, intake temp sensor...all these things might be causing a problem but I don't know, hence why I asked if anyone else did.

perhaps you should start by swapping your old tb, ISV etc back on.
See if it still does it.

[mikinoz]

Are you sure the manifold is correctly mated?

Yeah that was my next plan of action - which I just came back from doing, with no luck unfortunately.

Yeah, all surfaces down properly, gasket in, bolts done up, etc. Checked all that whilst fitting it because it was very tricky to align it in the first place.


Funny piece of news...I decided to unplug the MAF for the sake of it, and the car didn't stall. When the MAF is plugged in, the car drops to idle faster, idles lower, idle is unsteady and it stalls. When the MAF is unplugged, it drops to idle slower, idles at around 1000rpm or just under (at least until about 6 or 8 seconds have gone by), doesn't stall and isn't unsteady.

what is aerostart and where do you buy it from
that sounds like somthing i need to do!!!

maybe clean your MAF with MAF cleaner
