car idle surges a little and is rough..i reset the ecu and the problem comes back..whats the problem

heres a video for a power balance test. due the test both_x000D_
ways spark and fuel. I would invest in a noid light to see_x000D_
if the injector pulse is there or not. if not check wiring and_x000D_
connector. you could ohm the injector to see if the coil is shorted.

Just drove the car and when i got home the problem came back with the low rough idle but then i waited in the car for a few minutes and it went away..this problem is pissing me off

I would be checking the connections and wiring at the fuel injectors based on your description, when you changed them out you could have restored a faulty connection.
