I am having difficulties with my car missing every time I stop or the car is just idling. I have changed the spark plugs 2 times, coil packs, boots, and coil pack shell. I also replaced the fuel filter and it still has a miss to it. I don't know where to go from here. Please Help?

I have and the codes read and all it says are old codes nothing new has shown up. MY CHECK ENGINE LIGHT IS OFF. I DON'T REALLY KNOW ELSE TO DO. I DID HAVE A GUY SUGGEST TO ME THAT I NEEDED TO REPLACE THE THROTTLE CONTROL SENSOR. DOES THAT SOUND ANYTHING LIKE WHAT MAY BE WRONG?

I wouldn't go replacing parts just because
I would like you to get back to me with the codes (old codes will tell what was going on )
have you checked the crank sensor and relays
good luck

The only codes that I have are the ones that I got from auto zone and they include EGR valve low flow, throttle contol sensor, #3 misfire, #1 misfire, thermostat control sensor, and low fuel pressure. That is the only ones that the computer picked up. Thanks for all your help

Well egr will give you running rough at idle and may cause a misfire
you need to check it and also check fuel pressure
