whats up everyone another question hope someone could help me.
i want to know how set the injector sync because my truck is running rich

 

First, how do you know it's running rich? Is it throwing P0172 or 173? Have you looked and seen the ST & LT fuel trims way negative? Used a gas analyzer? Because unless the PCM or a spectrometer has told you this, it's probably not. About the only thing that'll make them run rich are failed O2's,or too much fuel pressure. Either way, it'll throw a code. CTS can effect it, but isonly used in OL.

Edit: Injector synchronization is done by the PCM with cam and crank inputs, and has nothing to do with fuel trims. And the Magnums batch fire, so it's not like you can time each injector seperately.
