Re: another problem

1. Weak Fuel Pressure - Check Pressure, Check Fuel Flow, Could Possibly Be A Bad Fuel Pump

2. Check/Clean Upper Plenum, Throttle Body (Making Sure To Clean Above/Below The Throttle Body Plate), And IAC.

3. Check Idle/Timing Adjustment - Use A Timing Light To Check The Ignition Timing, Check Idle With A Tachometer (Handheld Preferable Over In Car, Or Scanner)

4. Check Your Vacuum Pressure - Use A Vacuum Gauge And Go By The Specifications On Your Car

5. Check For Leaks Of Any Kind Near Or Around The Fuel Rail

6. Could Be A Intake Gasket Gone Bad

7. Pull The Fuel Pressure Regulator Vacuum Line Check For Fuel, If Fuel Pours Out Relace The Regulator

8. Check Spark Plugs - Look For Gap Bridging (Carbon Between The Electrode And Metal Tab) Could Cause Dead Cylinders

Hopefully Something Here Will Help You
