tps replaced, 02 replaced now what?

like i said ive been having idle issues, i got my car tested both tps and o2 were bad so i replaced them, and it wasnt cheap....so i get my car back from the shop today it runs MUCH better but it still for atleast 15 minutes do3es a very small up and down idle thing like 1-200 rpm. any reason why? so im looking for the next area to start in with my car. iv e got full exhaust, and a air filter cone(want to make box for it) where should i go next? i heard i should work on cooling, and pick up an aftermarket radiator and add aftermarket temp and some other guages? what are your suggestions?

I recommend some things that aren't so glamorous, but add to the rock solid reliability of the rotary.
- replace all of the vacuum lines
- have the injectors cleaned and tested; replace all the injector grommets and O-rings
- remove the TB and UIM and replace the gaskets
- do the water trick to clean out as much of the carbon deposits as possible

I agree with chuck. Even if its not directly related to the problem, it will help out how the car runs, especially the injector cleaning, and you will get to know the car a lot better. As for price, www.cruzinperformance.com does it for 12 each plus shipping. All told you're looking at 60-65, but they do an excellent job. It is well worth the money to get the injectors properly cleaned.
