Check engine light with MAF/injector change?

I replaced my injectors with 38lb and the maf with a 76mm with the proper sampling tube. I keep getting check engine lights that say its the maf and tp sensor (which were both recently replaced).But the codes go away when I turn the car off.
 
Questions

Try putting the stock MAF back on to see if the code is there. 38 lb injectors, is the engine stock? Any black smoke or black soot on the in the tail pipes?
 
hey steve

My engine is modified (big cam, ported heads, roller rockers, bored thirty over, headers, 255 fuel pump, and a few other toys). I dont notice any black smoke but, under my rear bumper has some black discoloration by where the exhaust comes out.
 
If you mean that the check engine light goes out or the continuous code disappears from the reader. Try the stock maf just to see.
 
No signal

The car will run with no MAF, after a few seconds it will look for a MAF signal, if it does not have a signal present it thows a code. Try with the stock MAF, if no CE light then I would suspect the new MAF.
