| Aug 18, 2020 at 12:11 | comment | added | Andrew | @GdD No issues GdD, I replaced the idling control stepper motor if that's what you mean. I used to have issue where the revs would sit up about 2k when coasting to a junction or lights, changed the stepper motor, fixed the issue. There is about 120k mls on it, engine is well-maintained, and the top end was rebuilt about 5 years ago. There is only one 02 sensor on this car. I did change 02 sensor about 5 years ago but it wasn't OE/Bosch as far as I remember, so I'm thinking it would be good starting point to see it makes any difference, especially now that I can see the traces from it. | |

| Aug 18, 2020 at 9:53 | comment | added | GdD | I'm not sure how I missed that, sorry @Andrew. I've gotten more coffee into my system, hopefully this will help. You didn't say what you did with the idle control, you just said you checked it. How many miles is on it? Also, have the O2 sensors been replaced? | |
| Aug 18, 2020 at 9:48 | comment | added | Andrew | I already mentioned the make model and year, can you read it again? It's a MULTEC single point injection that sits in a unit, forget I said carb. If you are referring to the breather system i.e checked, if you read it again I said cleaned it, i.e. cleaned out the muck in it, do you need a more comprehensive explanation or photos? | |
| Aug 18, 2020 at 7:34 | comment | added | GdD | Welcome to the site. What is the make, model and year of the car? You mention a carb, which would be rare on a car with an OBD system. Most cars with an OBD have fuel injection, do you mean an idle air control valve? What have you done with it, you say checked, does that mean you looked at it, replaced it, breathed on it, or what? | |
