1139 = Injector for cylinder #1 is failing.

4726 = excess fuel leakage at the rail.

-- Do an injector leak-down test to see if it passes. Fix the issues until it does.

-- Replace the exhaust gas pressure sensor (use OEM sensor only) + clean out its passage between it and the exhaust manifold.

-- If the engine has a delete program in it, then copy it out ans e-mail it to me for a review of what someone did in there. Bad programming is a plague and most people would swear nothing is wrong until it causes severe engine damage, and then its too late.
