Idle changes when warmed up (Long) 200

interesting post,

i have a 91 240 with 173kmiles..it has an EGR valve.

it starts everytime, first time. It will do 90 mph all day long, runs smooth as hell. Idles great in morning and whenever engine is cool. But, whenever it is hot out (live in florida) and I have to stop in traffic for a light or stop sign, it idles rough and wants to stall. I have cleaned the TB, replaced O2 sensor, checked everywhere for vacuum leaks, adjusted throttle plate, throttle switch and cable..still have idle problem. I never replaced the IAC valve or the AMM.

But I can tell you this..last week I paid $20 for an 11oz can of BG44k and dumped it in the tank just before driving 200 miles to visit a friend. I could tell the engine had a bit more power, but most of the improvement disappeared once the initial tank of gas was burned up. And I still have the poor idle problem.

I would be interested in knowing if you find the source of your rough idle.
