My 2001 Ford Ranger is running rich! CEL is on and it's throwing 2 codes: P1132 & P1152?

Coil pack, spark plugs wires are less then 6 months old. New O2 sensors, TPS, MAF, IAC, new fuel injectors and fuel pressure regulator! Idle rpm is about 1500 when engine is warm and surges when truck is in drive and drops extremely low in reverse. Black smoke has covered exhaust tips and the rich smell is very strong from exhaust while truck is running. Truck has 180,000 miles and is a V6.

You have already replaced several of the parts which can cause these codes so Il only list things you haven't replaced or need to check. The most likely cause is a vacuum leak since you're getting both a lean and rich code.To check for a vacuum leak do this: let engine idle, spray carb cleaner around every gasket, vacuum hose, and vacuum operated component. If the engine suddenly idles up, down, or the engine stalls whatever you just sprayed is where the vacuum leak exists. Be sure to check areas like the large air intake hose, air filter box and any sensor screwed into the box, tops and bottoms of fuel injectors where they fit into the fuel rail and the intake bosses, all intake and throttle body area gaskets, vacuum fittings on and under intake, pcv valve hoses, etc.Visual checks for vacuum leaks are sometimes impossible to find so carb cleaner works better. You can also use a small propane torch with the valve open instead of carb cleaner since its not messy.Vacuum leaks draw propane/carb cleaner
