Hello,
Check for vacuum leaks.
Did you check the Injector itself? and the Wire Harness. Will need Noid Light to test.
Also check fuel pressure and regulator.

Something I forgot to ask is, did you clear code after repair? If not it usually takes up too 1000 miles to clear or about 100 - 200 key starts.
If did clear code after repair here are other possible causes...
Weak Signal from Crank and/or Cam Sensor
Faulty Engine Mount
The IAC (Idle Air Control) Motor
