Im Losing Kw's! + Dodgy Idling

Urf

When i purchased my car, i took it to recustoms to give it a nice big service, all oils changed, o2 sensor checked, oil pressure etc etc

Dyno read 127.1kw

Then 1 month later, i noticed my car kept missfiring on high rpm's, especially in cold nights. Also had an idle where you could feel the car shake - stop - shake. my rpm needle stayed steady but could be old dodgy readout.

So booked car back into re customs.

Here is the result

recustoms changed sparkies gapped at 0.8mm and adjusted crank angle sensor to smoothen power curve.

Now the vibrating is worse, although its a hot day + black car and ecu has not been reset?

I asked recustoms to check coilpacks for cracks etc, however Ray was out and couldnt get a chance to speak to him.

Any idea's on wtf is wrong?

10:1 afr's...thats pretty damn rich...

anyway, the color of the car and the sun have nothing to do with your idle...

no shaking whilst driving. When i come to a stop there is no shaking and then it starts then stops, starts etc

Took car back to workshop, get knocking on idling. Workshop thinks it could be injectors or coilpacks. They checked coilpacks and found some slight marks but using their experience agreed that they are in good condition. Will be swapping coils with a friend and see result then.
