Question about 1986 Pontiac Fiero
Hi i replaced my thermostat and now it wont stay in its place it keeps turning sideways in the housing i dont get it and then it also hesitates at take off and after only running for a few minutes the exhaust manifolds turn bright red. I thought maybe the cat was pluged but i replaced it and it still does it what would cause these problems need help fast!!!! thank you Nick
The thermostat is held in place by a rubber seal around it and the access cap. One of those is allowing the thermostat to move freely.
The bright red manifolds indicate that combustion is occurring in the exhaust manifold. This is usually a retarded ignition timing issue. Check your timing and see if that helps the hesitation at idle.

The air-fuel sensor is located BELOW the manifold, on the side of the head pipe. You would need to be under the vehicle to see it.
That sensor is commonly called "bank one/sensor one".

SOURCE: 2004 caviler exhaust is glowing
Check the egr flow,if it's stuck in the open position it will cause a rough idle and over heated exhaust temptures.EGR= exhaust gas recirculation

That is usually from a clogged catalytic convertor and/or the pre-cat or collector that sits in between the manifold and the cat. If you left the pre-cat on, remove it and see what the result is.
