On my gray market (imported to US in 2001), the ASR will illuminate, after about 5-10 minutes of idling or driving, does not seem to make a difference, but NEVER does the car go into "limp mode". Restarting the engine when this occurs does not reset the ASR light and it stays illuminated. After doing searching about ASR problems, I find that those who's ASR light illuminates, their vehicle goes into "limp mode" Prior to having the codes pulled, can anyone direct me what might cause the ASR light to illuminate WITHOUT it going into limp mode? The only issue (not sure if related or not) I found while examining the engine compartment is that the MAF air tube on the drivers side was torn, and when I temp repaired with RTV, it corrected a slightly surging idle issue it was experiencing as well.
