haven't had a chance to check on the proms, i'll try holding one down and see if i get lucky, the weird thing is with the original ECU and the same proms the light would just stay lit??? just wouldn't idle without giving it gas, the new ecu with the same proms runs very well at idle and low RPM??? and i need to get on the Balancer, i haven't had time to check and wont till Saturday unfortunately

All the injectors on a bank have the same color wires. You should have a power wire (pink with a black stripe) and a wire that connects to the ECM. The wire that connects to the ECM is either light blue or light green, depending on which side of the engine it is on.
