99 GT hunting idle issues

[slvr99]

Have a 99 GT 3.8, recently changed the fuel pump. Now the car is actually running great but have an issue with the idle. When I rev the engine it hunts for the idle speed, the tach bounces between 600 and 1200 rpm before finally settling on 800. Now getting code 0102 MAF sensor low input, took it out and cleaned it, didn't help. Any suggestions would be appreciated. Thanks.

check for vac leaks and try cleaning the IAC, or replace it.
