Hey, I figured out that my low idle problem, goes away with head lights on or A/C on or even hot air. So car without headlights or air on. Idles at a stop around 300-500 rpm sometimes lower that it even shares.
When I have the headlights on or air on at full blast it idles normal at a stop. Around 700 and doesn’t shake.
Things I replaced are:
- PCV Vavle
- Idle Air Control Valve
- Checks TPS working and calibrated(.48 TB closed and 4.50 TB Wot.
- changed map sensor
- checks O2 sensor by disconnecting them and running the car and it ran the same with the same problem
If anyone has an idea on what it is, I’ll really appreciate it. Already been going on with a month with this issue and I can’t seem to find the issue.
