Rb25Det After Maintenance

[lareee]

Hi!

Couple weeks ago I drove my car fully functional to my garage and after that I have done few slight mods/mainentance procedures to it. And today as I started my car for the first time after I took it to my garage, it didn't work properly.

The car started nicely but immediately began to misfire on idle. Engine stopped misfiring on revs, but after couple times of revving the car stalled. Still starts nicely but if I even touch the gas pedal the engine stalls. The misfiring slightly decreased after the engine warmed up. Don't know if I'm just imaging it or is it just something I haven't paid attention to before but I can hear a slight "shhhhhh" after the engine stalls.

Stuff that has been done to the car after I took it to the garage:

-Plugs changed to NGK BCPR6ES, earlier ones was BKR5xx.

-ACC valve cleaned

-Throttlebody cleaned

-MAF cleaned

-Boost solenoid removed

-Camshaft covers painted

-Boostpipes polished

-Dump valve installed. Used to be just blocked with an aluminium plate

-Coils taped up because high rev misfiring

It's an RB25DET Spec2

Thank you for all your help!

Does it have standard ECU? if so do an ECU reset and start the car
