I just bought a 2003 sport edition last week. This weekend I drove from south Texas to Austin and about half way I stopped, put gas then when I started it up it got hot within seconds... But stayed normal all during driving so I was confused. Ive got a new radiator and a new water pump already and just replaced the thermostat today. Now all of a sudden when it first starts the truck shakes really bad, blows grey smoke and sounds like shit for about a minute or so then idles back to normal and sounds normal again without the smoke. All I've owned is toyotas and I've never encountered this problem before so I'm not quite sure if you guys have had this same sorta thing happen or if I should suck up my pride and just take it to Toyota...? Any advice?
Also, the Trac and VSC lights both stay on constantly. Not sure what that's all about.
