Hello again people of the Fiero Forum. I am greatly appreciative of all your support and suggestions but heres a new one. I have a leaking EGR tube vaccum seal so I figured I would go outside tonight and work on it a bit. Well I first began to spray a bit of Carb Cleaner as I was suggested. I little while later I noticed that my exhaust manifolds were glowing red hot. I dont think its supposed to do that. Any new thoughts would be helpful, thanks!

Any significant vacuum leak will cause the manifolds to glow red. A cracked EGR tube creates a big vacuum leak and there are hoses connection underneath the upper intake manifold that are great leak opportunties as well.

hi find leak quickly, glowing anything in our cars is not a good sign, if left alone will cause more trouble then it is worth, start simply inspecting and checking and you will find it ...

Mine has a faint dull orange glow if I pop the deck lid after running the car alittle hard and i'm on a real dark road........... If I drive normal and pop the deck lid on a dark road then it has no color but you can really feel the heat coming off them!
I have also seen other cars (newer with less miles) have this same effect (manifolds get super hot especially if your driving hard).

Now if it is glowing cherry red or even orange and your not out racing around then you have a problem. Vacuum leaks as well as incorrect igintion timming will cause this even a clogged CAT. Vacuum leaks are the most popular causes though.

Good luck....and fix that EGR tube!!!!!!!!

Glowing manifolds is not normal and will cause your headers to warp and getting those buggers off is a pain is the ass Fix that vacume leak and you will be good to go.


BTW your fiero looks just like mine... 86se ?

Check your caty converter. A plugged cat will cause that.
