2G Rough idle/misfire at random

[GriffLaserRS]

Ever since I bought this car it would cut out at random while driving. If i pull all the way to redline it feels like the car is hitting fuel cut at 4-5k rpms but doesent happen consitantly. The car will also hit a what feels like a fuel every time i make a hard right turn but not when i turn left. Now the car isint idleing consitantly. once out of every ten stop lights it will idle fine other wise it stumbles between 400 and 800. Im at a loss. The only code its throwing is exaust. Good luck with this one. Replaced ecu coil timing belt cps added drygas. What next?

Things to do when you buy one of these machines:

Buy new battery terminals and make sure they are tight
New spark plugs, USE NGK
New wires, USE NGK
Fuel filter
Do a boost leak test, if you dont know how, look it up on the site (easy to find)
make sure your air filter is clean

These arnt in any order but i would check the plugs and do a boost leak test first.
I seriously bought my dsm like 7 months ago and just recently have it running how i want. Dont get frustrated, just keep eliminating things and you will find the problem. Im more then sure by doing those things you will probably fix it, because i have done those things to countless dsm's of all kind and have had positive results.

Did these first but forgot to mention. Any other ideas?

im having the same problems for a while almost about 2 years and i've tried everything
and nothing..

ignition coils, plugs, wires, fuel filter, boost leak, and other stuffs that DSM forum members told me, but still nothing..

i'm guess could this be a result of bad turbo?, it only happeneds when its spooling.

also when i changed my water pump, it was gone but had bad idle, from 400~900 but it studder or fuel cut feel was gone, then it came back..

but idle is still off 400~900 and belts are installed correctly, my next guess is, is this due to poor Idle Speed Controller?
