stalling/loss of power evo 8

[Wayne'o]

well this has happened to me a few times over the last couple of months,

when coming upto tarffic lights,juctions, roundabouts etc i have dropped the clutch to change into a lower gear and the revs have fallen right down and sometimes recovers but also stalls on occasion too,
its started just randomly afterhaving the car for a few months and starting to annoy me,

anyone had this problem or know 100% what it is?
i have an idea to what it is but not too sure

thanks

Prob caused by an atmospheric dump valve I would imagine. Some evos don't like them for some reason but some evos don't seem to mind.

thats what i think it is, but just strange it has just started to happen,
i think if i come off the accelerator a little easier it should stop the problem.....

Sometimes I guess people just adapt there driving I'm not sure cos never had the problem and I ran an aps twin port and a hks ssq
