Just been out round some twisty roads and it drops power pulling out of a bend so i pull in to check stuff over. Every thing seems fine and it idles fine, temp is fine, no smoke etc.
Go to pull off and its fine upto 2000 rpm then as it starts to boost it gets a miss. Ive just replaced the distributor cap, arm and leads but not the plugs as they are denso iridium ones. Ive heard lately that the densos can fail on a boosted motor, so as soon as it cools down im going to have them out have a look but has anyone else got any ideas?
Oh and its still making full boost.

 

how much is full boost and what are the gaps on the plugs?

 

full boost is 0.6 bar, plugs were gapped at 0.028" Not had chance to check them as its dark and raining so will do it tomorrow now, i hope it is only the plugs.

 

as, no one else has oposted does it mean im right with the idea of plugs?

 

Right i swapped the plugs and no joy so swapped the brand new leads back to the old ones and its cured it so its the new leads that are faulty after only 300 miles. I wont menthion any names yet but i will depending on there reaction and what they do about it.
