evo 5 up and down on tickover.

[shockey]

have a problem with the 5 on tickover. usually happens after bein driven on hard or after being driven for a long period of time. also when boosting at high revs it momenterily cuts off and then goes on again. would appreciate any help.

do you have an atmospheric dumpvalve? this is common with them.

i have a hks sqv bov and this happens all the time

i think there is another type of recirculating dumpvalve which would solve this problem if this is whats wrong with your car
