Apologies, didnt really read / think about the post very well.

If the TPS isnt in the right range (under) it can cause it to stall. Extremely unlikely the TPS will have "moved" - although mine was out of voltage range and had never phsically moved. Maybe wrong from day 1.

MAP doesnt do much for the idle im told. I thought it did, but im told not. I still think catch cans are good for helping here though!

Dodgy idle can be a million and one things though, from vac leaks to faulty sesnors! Always a pain in the ass though!

My 04 S has a wandering idle some times. It was me that started the "$hitty in there" thread SB refers to and boy is it

I'm hoping a can of Wynn's carb cleaner and a filter clean with sort it out!

to be honest I havnt had a good look at the set up yet as not had it long but the problem will be the idle speed control valve, I go to this problem alot although not on hondas (as i said they dont break down lol). U can normally remove it and clean it with carb cleaner they get caked up and stick. Should be a similer setup on the s. Dont touch your cable or tps or you will be going to the dealer to get it set back up as if altered can have bad effects on over run.

 

Had a mitsubitshi FTO before the S2k which had the same problem, turned out to be the stepper motor. Replace problem solved. Not sure if the idle speed control valve is the same thing?

 

yes does the same thing just a variation

 

Yep dont fiddle with the TPS unless you have the tools to read the voltage

Id try the cleaning of the TB and ECU reset first.
