Pull codes........being that the light came on with the symptom, code should lead you in the right direction.

turn the key to the on position 3 times within 5 seconds ending in the on position & the odometer will give you the engine codes..no need for a scan tool

 

[SEEEEYA]

Gen III clogged cat issues are relatively common. 4k miles would generally be a bit early for clogged cats though.

Code reader is a good investment, especially if you have multiple vehicles. You can get a quality Actron or Innova code reader for $30+. I've been happy with my Actron CP9580. You can get them at Advance Auto for about $150 if you use Advance Auto coupon codes (tip: buy online, and pick up in store). In addition to reading and clearing codes, the CP9580 also records and plays back live engine data, displays live real time data, graphs live data, reads and clears ABS codes, has detailed code info, etc etc.

If you have a PC or Android phone you can use, ScanTool.net has really cool solutions. I'm planning to buy their OBDLink MX scan tool. It's supposedly theworld’s smallest and fastest OBD adapter, uses Bluetooth, can be left plugged in 24/7, and interfaces with cool software like Torque Pro, ScanXL, DashCommand, etc. I'll probably put a 7" Google Nexus 7 Android tablet in my Viper, with a floor mount or other stable mount, so I can see data like this ...

GOT THE CODE!!!!!!! alright all you techno geeks what does this code mean???? P0152 ? Got it right off the speedo like BLK04 said, hoping its an o2 sensor because it only happens cold and as it warms up,once im hot she goes good. maybe I could get lucky with a loose wire?

 

[pittVIPER]

That should be the code for the front o2 sensor on the pass side

[h=3]OBD II Code P0152[/h][h=2]Oxygen Sensor Circuit High Voltage (Bank 2, Sensor 1)[/h]

• OBD II P0152

Fault Code Definition
The purpose of code P0152 is to track the amount of time that the Oxygen Sensor or Air Fuel Ratio Sensor takes to go from indicating that the fuel control system is in open loop to rapidly switching above and below the 450-millivolt set point, thus indicating that the fuel control system is in closed loop. P0152 is set when there is a sustained high voltage signal from the Oxygen Sensor for a specified amount of time.
Symptoms

• Check Engine Light will illuminate
• In many cases, no abnormal symptoms may be noticed
• In many cases, the emissions will be elevated

Common Problems That Trigger the P0152 Code

• Defective Oxygen Sensor
• Faulty Oxygen Sensor wiring or connections
• Shorted Oxygen Sensor Heater element(s)

Common Misdiagnoses

• Oxygen Sensor is replaced when the problem is faulty Oxygen Sensor wiring or connections
• Oxygen Sensor is replaced when the problem is an over-reporting Mass Air Flow Sensor
