Hi all,
I have an 89 Sidekick JX 2-door 1.6L 8V TBI, and as I understand there are 2 normal hot idle speeds: 800rpm with nothing on, and 920rpm with headlights, fan, etc. on. I'm experiencing a small abnormality that I was hoping you could help me with: my car hot idles normally at 800rpm, and when the fan or parking lights are on, it goes to 920rpm like it should. However, when I switch from the parking lights to the main headlights, the idle drops to about 850 or so. When I switch it back to just parking lights, it goes back to 920, then back down to 800 with all lights off. What do you think could be happening? I'm guessing the CPU isn't recognizing the headlights being on so it's not initiating the fast 920 idle, and I guess the load itself is causing the normal 800 idle to rise to 850... Any input on what could be the issue and how to fix it would be greatly appreciated.
Thank you for your time and help!
