MK4 Escort with a N/A 2.0 Zetec running a DESK ECU.

Always had quite a stutter when initially applying power and also when changing gear (any time when power is applied from zero throttle really).

Recently its started pinking under load at mid to high revs in 4th and 5th.
Quite odd as I didn't think pinking would be possible with this setup, and it doesn't happen at low revs or gears either..... can't even provoke it at any other times and it doesn't even do it consistantly...any ideas?

Could an air leak casue this?

 

could be that you have a hole in the vacume hose from bgelow the thermostat housing to the inlet manifold. i had this and it caused the car to run really lean as it was sucking in air so may be worth you checking that its all ok.

 

Could be something like that....... dodgy inlet manifold gasket etc maybe?

 

sort it?

 

was about it today... can't find anything wrong

 

dunno then mate without seeing the car im afraid
