Are you positive all things are reconnected?

It may be that the throttle is not relearning correct. Can you check and see if the throttle body is needing to be cleaned. Did you have any running issues prior to the repairs?

its all clean and the vehicle is working well before i do this, i thing its the maf sensor. what do you thing?

We can try cleaning the MAF sensor as well. You would remove both battery cables. Clean the MAF. Hold the cables together for 1 minute then reconnect to the battery and test.

the maf sensor is clean went i take out its like new this is the 1 time i change the spark plugs on this vehicle and i do well maintenance this engine is like new everything is clean inside and outside,i just take out the fuel injector for put new spark plugs and put it back like its before but with new gasket thas all.

Since there were no issue prior but there are now. Something has to be a miss here. You may want to go back over all your work. Try the computer reset steps with the battery that I mentioned. If this still occurs then it is time for a diagnostic tool to figure this out by monitoring signals and sensors.
