just noticed on the left side of engine that the manifold gets super hot i mean it glows! at night!! and burning my spark plug wires and melting them! plus the car doesnt run good at all its real sluggish at take off and hesitakes alot durning aceleration... like theres a blockage also i have had the manifold gaskets replaced and i think before this it ran like that but no where near as bad as now... any idea what i should do i wanna fix it my self

 

Runnin' really lean! Not cool!

 

get it fixed, before it costs you alot of cash

 

would say either lean or retarded
and I don't mean stupid type of retarded

if you can see what the voltage reading on your o2 is
while not perfect if your seeing really low volts and you know the 02 is running right your running lean

also check the timing

 

Your cat could also be clogged Make sure its not, I heard this problem and it was just a clogged cat. Hope it helps

 

My friends 350 used to do that, but that would be after racing, his motor was built up and that would be after racing up and down this corn field side road. You could almost light a cig off of it. But his always ran well. Like said above I would check out to see how lean it's running and check that timing. Before it's to late and something gets seriously messed up, like a head
Good Luck

 

my money is on a plugged cat convertor. ive seen it on a couple different vehicles.

 

a plugged cat will glow too.

 

Check your timing and cat! When we first did the 3.4 swap had some running issues with timing. We got the ex. manifolds so red. No damage though! It was the timing for us though!

Mom's 2.8 had a bad clogged cat. Car would barely run. Flat would not accelerate. Cat glowed, but manifolds did not.

 

i pulled the coverter off and looked at it and wasnt cloged at all... i guess i will check the timing out and see if thats the problem... my 02 should be working right because i recently replaced it
