Vacuum delay valve

[walkie]

Hi, my car had this fitted when I bought her and can't decide is it really necessary on a tiv? It keeps my idle revs on 1100-1200 rpm for a couple of secs when stopping as it slowly releases the vacuum.

Here's an ebay link to the valve: this one...]

Tell me I don't need it

Thanks, now I need a longer vacuum pipe, this bleep is just sitting in the middle...
How I love the full TVR service history the car came with... I had to change a camshaft with followers, rockers and shafts, timing gear and chain, distributor, leads, plugs (they put some denso in), fuel pipes, clutch, headlights. All these on a 62k car with sh up to 60k...
At least its quite sorted now and what a blast to drive

Thanks Daz, bought one.

Oh yeah, took all winter to sort them all out, but since then the car hasn't skipped a beat and I started to think these tivs are reliable
It's a bit overkill to use a 500 for daily commute, but the jag xjr can sit in the garage until next winter...
Oh, forgot to say, one of the precats was broken and blocked the exhaust so I've removed them both, nice deeper exhaust note is the reward. Also fitted a hot start kit therefore I dont need to pretend I'm checking the fluids after filling her up with gas
