reverse switch in transmission is bad. see if it will start in reverse, if It does its definatly the switch.

Check the MAS (mass airflow sensor), clean it, maybe it will help, but it could be a computer problem too

its the top one inside the transmission pan. u need to drop the pan to get to it. there are three. one by itself one ontop of the other. its the one on top easy to get to.

I think from under because no room from the top.

How do you know the thermostat is ok? If in doubt replace it. Water pumps are a even bigger what if. Did he do a radiator flush? Cooling system flush of the engine? Cooling fans come on at what temp and go off when? Replace the engine temperature sensor? 6 years old is bound to have sensors and such go bad.

The fault has to do with your secondary air injection system. They most likely cause is a bad air pump

I have an 01 impala 3800. After 2 months of searching for the source of the misfire that was causing my car to surge, stall, and generally not run well; I rebuilt my tranny, because it needed it, and in hopes of finding out something more. Well, when I put everything back together I stumbled on to a fuel leak on the rear fuel rail fuel supply line connector. In the process of trying to figure out what the problem was I\'ve been through many, many forums and a hellava lot of people have had the same problem and racked their brains and spent thousands of dollars. Long story short, I replace the connector with a $20 kit, right off the shelf of the local parts store, and the problem is fixed.

tune up,vacuum leak,fuel filter,battery and connction.

probablemente wl problema que tienes es un mal termostato. Cambialo porque parece haberse quedado pegado en la pocision de cerrado haciendo que se caliente tu carro y que las mangueras se pongan duras debido a la alta presion de coolant super caliente. Un cambio de termostato arreglara tu problema.

probably a gasket that seals coolant behind cover. I don't remember if there is a freeze plug there.sometimes a head gasket leak can do the same but not very common.

check your door controls, they are known to short out. When you try to boost it after it has died, have you disconnected the battery for a few minutes first? Had this problem with an 02 envoy when the temp dropped below -20
