I'm going to throw this out; two other situations can cause erratic idle:
1. Crud can build up where the throttle body plate seats against the wall and allow additional air thru at idle. It only shows up after hot becuase the ECU is throwing additional fuel (cold start injector) into the engine before then, which masks a lot of these type problems.
2. Vacuum leaks are VERY common with the fourteen thousand miles of vacuum hose on these things. Go all over the hoses with an UNLIT propane torch; if it idles up when you pass over a spot, you have a leak there.
Good luck.
