rough idel 2

lets try this again only shorter. I was just on a trip to ohio from minnesota 1600 miles the car ran great except, it had a super rough idol when the car was warm and the outside temp was above 75 deg, I checked the forum and it said to check the Iac and the throttle body and the egr. well the Iac is new and the throttle body is clean I cleaned it but it was'nt dirty at all! and the egr was nice and clean as well, the mas appears spotless!! no codes not even a soft code. the car only rough idols for a few minutes then smoothes out, it will die a few times during the rough idol. the car just did this again after the trip home and a week later it was 80 deg today this appears to be a prob only when its warm out and the car is still warmed up from a previous running! does not do it at all if the outside temp is below 70 deg. sorry for the spelling but I have had a few and I do not spell well anyway. any help would be appreciated.

Now onto my post. . . . . I posted this a year and a half ago. I followed peppermrj's advice ( Thank you ) but unfortunately my car still does this every so often and I still haven't figured it out. Drives me up the wall when it happens. If you solve yours, I would love to read about it!!!!!!!!
P.S. I logged in three separate times to post this. Does this happen to anyone else or is it my bad luck??
On warm to hot days, Conti will run rough usually stalling, and after a few attempts to keep it running, will run smooth after 30 seconds or so. Only does this once in a while and runs great normally. I first thought the fuel tank may be vapour locked but gas cap wasn't hard to get off. There are no check engine lights or error messages. Just tough to keep it running initially again once in a while and only on hot days ( 85 fahrenheit plus ). P.S Conti's only got 53000 miles and runs like new except for this little issue. Fully serviced by Lincoln to date so it got what it needed when it needed it so far ( flushes, tune ups, change ups etc. )
Any thoughts anyone?

Re: 95 rough idle and stall upon start up
Could be a dirty or sticking Idle air control valve, Throttle body, or EGR valve. All can be simply cleaned. Good luck.
