Ok so I have an 89 toyota with a 22re, I have replaced the Vane sensor twice, replaced ecu, fuel injectors, Fpr, tps. The car is throwing out black smoke so I know its running rich and you hear loud explosions when they detonate in the exhaust. For some random reason I continue to have codes for the air flow sensor and the intake air sensor. I also get codes for the Vss but the speedo works albeit not perfectly. Im searched and looked and am looking for some help to see what I may have overseen. Any help is apreciated

This is on a M/t 4x4 aswell
