Vr auto shuddering and stalling

[Jahwah]

Hi all

I've had my vr for about 5 months now and last week started acting up. When slowing down to stop it will dop revs and then go back up then drop down again and occasionally it stalls and is hard to start back up. Any ideas what this could be? Any help would be much appreciated

Have you checked the fuel pump?

If your battery is on it's last legs it can cause this problem as Commodores don't like low volts, also I'd clean the throttle body as they need cleaning every now and then. Plus do a fault code check and see if any are logged: Checking error codes VR/VS (Revised)

The battery is only new bought it when I bought he car. And I haven't checked fuel pump yet but I hall do that when I'm home from work and throttle body will get cleaned to

I also got told by a friend who had a simolar problems the fuel lines may need replacing? Is this true?

Fuel lines should only need replacing if they get bent or squashed which is pretty rare - they are steel tubing. Don't forget to do a fault code check as per the link prev supplied. If the fuel pump was playing up it would be evident when the pedal is to the floor and fuel demand is at a maximum - you problem occurs at low revs when fuel demand is low. I'd closely examine all vacuum lines around the throttle body as they can split and leak. How are the plugs and leads?

clean and tighten your battery terminals such a common cause of this in vr's

Brand new plugs and leads put in 2 days ago. I reserve the computer today as well and possibly changing battery terminals to new ones tomorrow if I have enough cash. I will check th vacuum lines tomorrow when the sun is out again after work lol

Throttle body cleaned, batter terminals replaced but still doing it! Only seems to do it when slowing down at about 20 k's
