What causes a car to run at rough idle?
Modified exhaust pipes or baffles can change the back-pressure in the system and affect the mixture. Use stock exhaust pipes, and make certain the mixture is set for the back-pressure supplied by the exhaust system. Refer to manufacturer’s specifications for year and model-specific information and procedures for these tests.
Why does my car idle with an exhaust leak?
The smoother idle may only be your perception. As stated, exhaust leaks near O2 sensors can offset their readings and therefore upset the fuel mixture. You might address the exhaust leak and recheck for the problem. You must be logged in to reply to this topic.
Which is exhaust pipe goes to the right?
The early models (03-06) are 4-2 with a cross over pipe. If he does have a newer model (07-08) then I see more of the exhaust going to the right pipe than the left due to the flow characteristics.
What to do if your exhaust gas recirculation valve fails?
The fix is to service the valve regularly and make sure that it is clean and fully operational. This is the Exhaust Gas Recirculation valve, which sends some of the engine’s exhaust gases back through the intake system to lower the vehicle’s emissions. Over time, the EGR valve can fail in the open or closed position.

What should the rate of revolutions be on an idle engine?
When you start your engine, and just let it run without pressing on the accelerator or putting it into gear, that is idling. A properly idling engine should be able to maintain a steady but low rate of revolutions, somewhere in the vicinity of 1,000 RPM. Your tachometer needle should be steady and not jumping around.
What does it mean when your car is idling?
Let’s start with a definition of idling. When you start your engine, and just let it run without pressing on the accelerator or putting it into gear, that is idling. A properly idling engine should be able to maintain a steady but low rate of revolutions, somewhere in the vicinity of 1,000 RPM.
