Rough Idle in 1999 Prelude

I have a 1999 Prelude, non-SH. Quite some time ago I got a check engine
light. I pulled the code and it indicated a problem with the CKP/TDC
sensors. Despite that the car ran fine.

Last week I found the car to be idling roughly; it's RPMs were lower than
they should be. Once I got home, with the car sitting in idle the check
engine light started flashing. I checked the code again and it returned the
same one for those sensors.

So I finally had the sensors replaced. As I approached home the check engine
light came on yet again and when coming to a stop the engine was idling
roughly. When sitting at home I revved the engine slightly; it hesitated a
bit and the revs then dropped back and the car died. I am still able to
start the car and drive it around.

The thing to note is that the car is fine when cold; it starts idling
roughly when it gets warm. When driven the car seems to run more or less
fine; I get the feeling that it isn't quite right, but the problem is really
only exhibited when I come to a stop and the car is idling.

I am hoping someone has any idea what might be causing this. Any advice
would be appreciated.

 

yes its because you bought a honda just kidding that sounds like a TPS my
friend. They are pricey go to the junk yard and see if you can find one
decently priced.

 

if you changed the tps allready make sure its adjusted properly it must be
addjusted perfectly if its a hair off it will act funny apon acceloration
and idel.

 

I had a low/rough idle on my 2000 Civic SiR, Replaced Iac Valve (didn't
fix), had base idle adjusted to highest level (didn't fix), finally I
cleaned out the throttle body with some throttle body cleaner (or carb
cleaner) and the idle was good. There was a buildup of carbon all along
the bottom edge of the butterfly flap causing at idle to idle lower due to
not enough air getting past.
