So, I opened up the garage door a little, started up the TA and it started idling reeeallllly low, starving for fuel it seemed. I could also smell a hint of fresh gasoline in the garage while it idled. so i turned it off, disconnected and connected the battery, started it back up, and it was fine. I believe there is no leaks as far as I know, but it drove perfectly fine after it started back up..

At first, I thought it was just out of gas since my fuel gauge rarely works. The 'check gauges' light will come on and the fuel gauge will drop. but when light goes away every 20 seconds or so, itll give me a reading on the gauge.... weird........ anyone have any ideas? or similar problems?
I'm not driving it out in the snow, just checking up on it every now in then....just purchased from dealer.
thanks in advance!
