Thanks guys.

I will get underneath and check the joints - only done 35K miles so it would be disappointing but who knows....

Having successfully cured the hesitation on my chipped and inter cooled Puma (leaking inlet manifold seal) I have had the injectors re-programmed and the engine runs really well. It pulls strongly tho ...

This post has been a long time in the making but at long last I think I can report an improvement in my Defenders performance.

The hesitation when accelerating and when under load was getting progr ...

Hi Meeerrrk

With the EGR blanking plate fitted does your warning light show on the dash or has this been overridden by disabling the EGR in a re-map? Not sure I want a warning lamp on my dash all ...

Hi Hornet, Blackwolf....

Hornet - The temperature issue maybe relevant. Ever since I have owned the car the temperature gauge sits just slightly above the midway point. It never varies and the the ...

OK. So I finally got round to changing the VCV on my Puma 2.4 to see if it would cure the hesitation I have under acceleration or under load when the engine is hot.

After the valve was replaced - ...

OK, so the engine has now been serviced and the hesitation is still there. I have obtained a new VCV and will fit it myself.
