Why is my exhaust manifold glowing red?

Asked by Yota_i_am Mar 05, 2015 at 12:19 AM about the 2001 Toyota Sienna XLE

Question type: Maintenance & Repair

A week and half ago my van started
losing power like I was taking my
foot off the gas on the expressway. I
had it towed to a muffler shop where
they put a new catalytic converter
and first muffler. Two days later The
van was running rough when I first
started it. The exhaust was
sputtering. Last night I detached the
second and final muffler. The van ran
fine on a 15 minute test drive.
Tonight on a 15 minute drive with the
muffler still detached the van ran
rough and the exhaust manifold was
glowing red again. No check engine
light, engine temp reads fine.
Changing spark plugs tomorrow but
that seems like a long-shot. Any
ideas?

scan the computer for codes anyway. sounds like a very rich or very lean condition. could be 02 sensor, or possibly the timing is off.
