Check your Idle Air Control Valve....

Would that help the boggin out thoe?

Does anyone think its my fuel pump?

If you are sitting at a light and the RPMs are going from 500~900, the IAC would be my first thought.. Or does it bog at different speeds???

Its does both thing..boggs out then sittin at a light the rpms race up

Bring it back to where it was fixed tell them to actully fix it this time and tell them you are not paying them anymore.
