Hi Derrick, Have look at the rubberized plastic intake manifold ducting. between the throttle body and the air flow sensor. These ducts break and let in un metered air and cause a lack of power and and even misfiring. If it's broken underneath and difficult to detect or see it may have gone unnoticed. A leakage of air from there can cause the fault readings recorded during a scan. Regards John
YOU COULD HAVE AIR LEAKS AFTER THE MASS AIR FLOW SENSOR OR IN THE EGR OR PVC SYSTEM.YOU HAVE A MECHANICAL FAULT AFFECTING ONE OR MORE CYLINDERS EXHAUST LEAKS LOCATED IN FRONT OF THE A / FS OR HEATED OXYGEN SENSOR LOCATION.FUEL SYSTEM SUPPLYING TOO LITTLE FUEL DURING CRUISE OR IDLE FAULTY FUEL PUMP OR FUEL FILTER.FUEL INJECTOR ONE OR MORE DIRTY OR PRESSURE REGULATOR HAS FAILED.THESE ARE THE POSSIBLE CAUSES TO YOUR PROBLEM.
P1130 A/F Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1). Some possible trouble areas include: open or short in a/f sensor circuit, a/f sensor, air induction system (which it looks like you already checked), fuel pressure, fuel injectors, or your ECM (Engine control Module). I can send you steps to check these but i need your email address cause i can not post them on the internet do to copy right laws.
