99 Mustang GT 4.6L
I am continuing to have idle issues and is worsening. My car seems to idle at about 700. When coming to a stop, it will jump down to 500 and stutters. The lights on the dash seem to dim also.
List of what I've replaced:
- Power Steering Pump(leak)
- Fuel Filter
- Spark Plugs
- Battery and Cables
- IAC
- Alternator
- TPS
- CAI
- Throttle Body
- EGR Valve
- Serpentine Belt
- Ignition Switch
- and others
I still can't pinpoint the issue. Thinking it could be a vacuum leak but checked, didn't find anything.
Thoughts about what it could be:
-Fuel Pump(low pressure)
- Vacuum Leak
- Bad Ground
- Bad AC
- Bad O2 Sensor
- Bad Coil Packs
If it is a vacuum leak, can you help explain all the hoses that need replaced(still novice).
Thanks
