Hi all can anyone help me out,my Z tends to stall under harsh braking,if the revs are kept up this doesnt happen.She has had some extensive work carried out on her.So far cant seem to pin point the problem,any suggestions?

 

Check you brake booster and vacuum lines for leaks.

 

Thanks will do,forgot to mention it tends to happen more when she is hot

 

I'm wondering if maybe it's electrical. The alternator maybe.
Harsh braking would engage the ABS system and therefore cause a huge demand for power from the electrical system. Revs being kept up=not stalling sounds like the alternator.
I know when my alternator was going bad, harsh braking would cause everything in the car to shut off momentarily when the power was required.
Just a thought.

 

Thanks heaps,that seems like my problem as she cuts out momentarily aswell.

 

I agree with Rizz. I just changed out my alternator last month. Braking dropped my revs causing to almost stall.

 

I had a similar issue, but it wasn't the alternator. It was the battery. Battery had gotten a bit weak in the knees and wasn't holding an adequate charge. It hasn't happened since I bought a new battery; which was 4 years ago. I had almost forgotten about that little gremlin. You're definitely on the right track with the charging and electrical system.

 

Thanks alot guys,you've given me a few possabilities,shes off to the shop next week.Thanks heaps
