    Idle issues

    So I have read around this forum and on the net about idle issue. I have read that it can be a multitude of things. When I ran my check engine codes it said it was my VSS and my 02 sensor. I have sense replaced the 02 sensor and still have issue with my idle. The VSS I am going to replace tomorrow on my day off. I had one guy at a store tell me it was my TPS sensor. I mean if the ECU is not throwing that sensor code where should I start?


    P.S.
    Please no flaming I really have read around about what could be. I just do not want to spend money when I do not have to on sensor that are good.

      The VSS and o2 sensor have nothing to do with your idle problems. That's like trying to fix a flat tire by replacing a headlight bulb.

      Read the "read this first!" thread at the top of this section. You will find a link to a thread that tells you how to set your base idle. It involves cleaning/adjusting/replacing the IACV and FITV. The TPS may be part of it as well, but that would throw a CEL I believe.

        well i ran the cel and I got a code 17 and 41. I have already replaced the 02. Senssor about two years ago and never reset the ecu.

Am happy that its not the map sensor or somethingg else expsensive. Will keep yah posted

          41 is the o2 sensor... so either that sensor went bad (if it's a Bosch, that's almost guaranteed... you have to use either NTK or Denso.) or there's something wrong with either the wiring or the ECU.

          Inspect the wiring. See if you can get your hands on another ECU (after resetting yours, of course...) If neither thing fixes the problem, get another o2 sensor. RockAuto.com has a good deal on a Denso sensor.

            Well just to update I got my VSS on so now the speedo is working, I also painted the valve cover red and replaced the the seal. Next I have to take the rocker assembly off to get to other gasket. I also have to get the gas filter onto. Of course this is if the weather will let me. I have also been searching around to find out if there is a wing installation guide out there. I will post picture tomorrow when there is light out.

              I noticed erratic idle when I added some coolant to the car at one time. (had air in it) Bled it, and it stopped. You could check it out. It's free!
