Having problems with your GMC Yukon XL ?
I just changed the intake manifold gaskets,put everything back together right,marked the distributor while taking out,put back the same way.I fired it up and the Yukon 5.7 has like a rough idle and sort of a hitching under 2500 rpm I hooked a diagnostics tester to it and the code read 1345 and I dont have a guide to identify codes.What do you think???
