I have another post running about my rough idle. I have tried/checked:vacuum leaks, new plugs cap, rotor, cleaned throttle body,AMM, snorkel. Replaced 02 sensor,air filter and other ideas I have learned from search archives.

Now, I have noticed it seems to be idling rough when warm. And, the main fuel pump is very noisy. I have not changed the fuel filter yet, so maybe it is straing to get past a clogged filter. At the same time, the exhaust note, is not one of a smooth idle, but it kind of pops and misses a little and the exhaust pipe shakes with the rough idle, as the fuel pump sings away. Either the pre-pump is not working(I have 12v at the pre-pump) or the main pump is still working, but ready to crap out? It is probably original, 110000 miles. I am going to see if the symptoms are there when it is cold. Thanks for all of the help.
