Hi Mandy
I have had something similar on a Nissan, no lights and no power.
Does it make any unusual noises when putting your foot down? Pinking noise, whooshing or hissing noises?
I take it you have had a code reader plugged in?
Wondering if the MAF sensor is reading air intake incorrectly, giving this a clean with isopropyl would be beneficial anyway, but these usually these throw a light and go in to limp mode. You LC has not gone in to limp mode? can you build up speed with it?
Also have you checked the car when the iginition is on that the CEL light actually works?
