hi, don't want to give up on my evo 4. it's a 98 lancer coupe with an evo 4 engine. tried almost everything and i couldnt find the reason for the rough idle. really hope someone from here could help.

boost leak= no leak
test another iacv / throttle body = still rough idle
test another coil, wires and changed plugs = still rough idle
checked fuel pump, filter and relays = looks fine
test another maf = still rough idle
