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.
