2G power transistor

[9520g]

My car has been misfiring and the rpm needle jumps up and down, I have searched and read where its located but no luck finding it or any picutres of what it look like. Can someone point me in the right dorection so I can test it and also if it s that can that be causing all these problems?

easiest way to find it is looking right by the fuel rail you should see a giant harness/plug and TADA!!

Is that the one that makes the ticking sound once you turn the car off?

i was under the impression that clicking sound was the ecu shutting off which is completely normal (please correct me if im wrong)

Power transistor makes no sounds. The turn off ticking is from the MFI relay and sometimes also IAC. Power transistor connector: http://www.dsmtuners.com/forums/att...l-connections-7.-power-transistor-medium-.jpg
