1) Nope, it does not happen after I fill up
2) Nope, it does not happen when I press the brake
3) Only happen when the car is warm up.
FYI, the rough idle doesn't happen all the time.
Again, I had EAS run both actuators and they are in good shape (so i dont think is the actuators)
got me look into the MAP Sensor and the coil packs, I had the spark plugs change about 5 to 6 month ago but didnt change the coil.
this car does not have MAF sensor.. so i cannot think anything else relate to current symptom I am having.
