3100 Thermostat Help

[Synergy6915]

With the help of a friend we replaced the thermostat on my 96 lumina.

 

After we took the throttle body assembly off to replace the thermostat the gasket broke apart so had to put a new one on.

 

Now when i start the car it starts fine but we hear a high pitch air noise and the car dies. Pushing slightly on the gas peddle causes the car to idle up to the extreme but the car quickly goes back down and dies.

 

Any help would be appreciated.

 

Thanks.

sounds like u got an extreme vacuum leak, and the car is running so lean it dies, but i could be wrong, or it could be trying to make the correct air mixture and actually dieing from flooding it

Ok so if thats the case could taking off the throttle body assembly and replacing the gasket cause that?

 

The old gasket was a plastic type material and had no sealant on it. The new one was a cardboard type gasket and claims to not need sealant either.

cardboard type? that might be it right there, is it a GM part?

[Synergy6915]

From Oreilly's Auto Parts. It was not a gm part.

Did you put all the TB bolts back in?

Did you put all the TB bolts back in?

 

Yeah, I forgot to tighten mine back up when I changed the t-stat and the car ran real shitty- high idle and got real hot. After I tightened the bolt it ran like a champ.

Fixed. Turned out the gasket had accidently been installed upside down. Dont ask me how that happened but yeah.....

 

 

Now the car runs

 

Runs kinda nice too with all the carbon cleaned out from the inside
