I have an ls turbo in an eg si. The ls has wisceo pistons, eagle rods, 440 injector and have neptune as my tuning. my problem is when the car is cold it sound like ---- (misfire)
when the car get to normal temp above 180, you mess around with the plug wires and then it will work fine a drive fine no miss fire. I've changed the spark plug, wire rotor and cap. Today i put my gsr dizzy and plug wires on my ls turbo and it did the same (misfire) so does anybody knows whats wrong

 

do u have resisted injectors that are suposed to use a resistor box or high ind. that are plug and play with a eg?

 

yes i do and its connected right

 

bump anybody
