My engine surges at idle on my 2.5 V6 and will sometimes stall. I have had the engine light codes checked and it said EGR valve, IAC, Oxygen sensors, and a few more. I have replaced the EGR, IAC, and both oxygen sensors and the engine is doing the same thing. The check engine light is still on but I haven't had the codes rechecked. I have exhuastedly checked for a vacuum leak and have found none. I'm out of options. The car runs fine when it isn't idling. Where do I go from here?

How did you check for vaccum leaks?

Remove the negative battery cable for 1 hour and then reconnect it and let it relearn.

If that dont work and there are no vaccum leaks take it in and have the dealership look at it the EGR may need to have a relearn done on it to learn where the closed position is.

I sprayed carb cleaner around all the vacuum hoses and fittings and found no difference in idle. I'm am hoping to get a vacuum gage tomorrow at work and check the actual vacuum from one of the hoses coming straight off the intake. Thanks for your response!
