| Sounds like a sensor problem of some sort. When you start the car you are in open loop. Meaning the tune parameters are fixed and are basically ignoring your factory sensors for roughly 120 seconds or so. The fact that your car starts having problems shortly there after and goes back and forth tells me there is a bad sensor or something along those lines. I'd get the codes scanned they will tell you where your problem lys. |
