My car's a kangaroo

[Ka` 0]

I know this problem is often asked about, so am sorry.

I have dressed in the appropriate attire for the insults hurtling my way :oops:

 

I've tried to read upon this as much as I can. But my car keeps on cutting out.

Occasionally it splutters as well, with the revs going all over the show.

So the kangarooing seems to coincide with 3rd gear, about 2000 revs and over.

It does sound as if the engine has died completely, as in, no noises come from it at all

and then it jumps back to life again. It is just very unreliable at the moment.

 

I cleaned the ISV as per instructions found on here, I was surprised to find that the ISV

was not actually coked at all, there was dirt there, but nothing I was expecting.

 

Now, a garage told me that the HT leads seem to be in poor condition. When I asked him

whether he was going by their looks, or whether he knew for sure they're not working,

he wouldn't give me a straight answer.

 

I've replaced air flow meter, coilpack and the hall sender less than a year ago...

 

Could someone offer me some other clues of where to look? I am getting slightly

frustrated as I have to rely on the car daily.

 

Thanks and sorry for creating yet another thread

Cheers,

Sounds like an air leak to me.

 

Get the lambda probe checked too.

 

VRs have a slight bucking around the 1500-2000rpm mark anyway, but it's more apparent in some than others.

I am a kangaroo...

 

though the doctor told me not to think like that anymore. he said its not healthy.

Thanks Kev and Matt,

 

I knew of the slight VR6 bucking, but the cutting out is so bad that I get thrown forwards at the seatbelt when it does. Quite

forceful, sudden stopping, is what I mean to say.

 

I've put it in for fault codes. I'll ask them to check the lambda sensor as well.

 

Cheers again,

Here's something else you can try.

 

Take the ISV off and make up a couple of lengths of wire with small female spade connectors on one end, and bare wire on the other.

 

Connect these wires to the ISV, hold down one wire onto the battery + and then continually pulse the other lead onto the battery negative (on/off). Do it about 40 - 50 times. If at any time during this pulsing the internal valve jams open or closed, that's the reason for your cutting out and you'll have to replace the valve.

 

A clean valve doesn't always mean it's 100%. They absorb a lot of heat from the manifold and can sometimes jam up.
