So i just did all new injectors in my lb7. Got it back together and its loping real bad. After i give a little throttle the loping goes away but at an idle its aweful. So I checked for leaks, nothing. Wont hold a prime either. So i just got off the phone with this diesel mechanic at tires plus and he said I had to "write down the numbers from each injector in each cylinder so I can reprogram the ecu to each individual injector." and he continued to tell me basically how dumb of an idea it was to take on such a job by myself. and then told me i was gonna have to take it in so he can pull all my injectors write down the codes and put it all back together and reprogram it. UMMMMM WAY EXPENSIVE, u'd think someone may have mentioned this small step in the DIY LB7 INJECTORS...?
