yes another rough idle question

[scarecrow]

i did do a search but did not find out much...i have a 1995 AWD astro it starts and runs fine except for idle. first thing in the morning it will idle fine once it warms up it will not idle it sound like it has an awsome cam in it and the exhaust is very rich. if left alone it will stall. driving around it runs fine except for when i stop for a light or in traffic then i have to bump it into N and give it a bit of gas. no codes are being thrown. so far i have done plugs , wires , cap , rotor , pcv , removed egr and cleaned and checked for vaccume leak and found nothing. any help at this point would be great.

i am having the same problem it runs and idles fine when cold but when warmed up it idles like dog shit it will idle very low like 350 rpms at stop lights but driving is fine i did the same thing you have done and it did not change my idle when warmed up i have changed my IAC it did the same the one thing i have not done yet is change the o2 sensor. i have a 3 wire heated o2 sensor.

A rich condition is a clue. I'd be checkin' the fuel pressure regulator.
