The sputtering would too many things.

A rich condition will NOT cause excessive exhaust heat.

Are you sure? I said S14, which means the cat is IN the exhaust manifold, and excess fuel on the catalyst would melt/damage the unit causing the the manifold to over heat.

not that i've experienced it, but i've heard of rich condition causing still burning mixture to escape into the header on domestics, causing it to glow red

^^mr knowitall again... greeeaaaat.

a rich condition CAN cause excessive heat.

the distributor could have moved - retarded timing makes that shit glow like that.

or the cat clogged/piping kinked off. i actually seen a muffler innerwall material melt down in front of the stream and cause it.

injector issue, etc.

I would start at the timing.


My SR glows red in the dark the mani and turbine sometimes do... I was tuning a gtir swapped sentra last week and that car had the o2 glowing bc the fellas crank pully rotated and the timing marks were off and he didnt know any better. came over and that shit was RED - i was like so yeah... we're gonna need a ruler, a screwdriver and a plug wrench - i set that bitch to TDC according to my screwdriver, measured the 20 marks distance to the stock tdc mark - marked from the pin over, and set that sucker to "Steve's 20 deg"

hooked up my knockometer, lm1, and ostriches, and did er up.
shit runs its balls off now.
