Thanks for the info
Okay, so if I understand you correctly you had the battery and alternator checked and both are good.
The light does not have to be on to have thrown a code. So you check the codes with a scanner though and no codes were thrown.
Is this when the engine is still cold, say the first start of the day or does it do it all the time even when the car is warmed up?
At 60,000 miles, you are supposed to replace: Air cleaner filter, fuel filter, spark plugs and a few other things, but those don't relate to your condition.
First, take a spray bottle of water and start the engine and mist the water all over the plug wires and see if it anything changes. Let me know.
Some of the things that can cause a rough idle are the throttle position sensor, mass air flow sensor, a vacuum leak, the EGR valve.
My suggestion is to do the normal required maintenance above to include the wires. Look at each plug though to see how it looks and let me know.
Then answer the above it there is no change. Your thoughts?
