Asked by Jul 16, 2012 at 12:23 PM about the 2002 Ford Taurus SE

Question type: Maintenance & Repair

Hello all,

Daughters 2002 Taurus AC pulley failed.  I got car AFTER a local (to her work) repair shop started work to remove/replace AC compressor, estimate too high and she asked dad to fix.

Clutch assembly with pulley $65+belt $28

After reassembly and fired-up the car noticed it wanted to run very rough at idle but would smooth-out above 1K RPM.  
Thinking the CPU needed some time to re-acquire data after battery disconnected for 3 day's let it run for a couple of min while checking for broken wires or disconnected vacuum hoses.
All of a sudden noticed that the rear exhaust manifold had gotten cherry red........Do not have a code reader accessible till tomorrow, but thought of asking as what I may have disconnected while lowering the front part of the cradle to cause this.
Any pointers greatly appreciated.
A.
P.S. Engine was running perfect until the pulley froze-up and tossed the belt (engine shut off as soon as the belt ripped).

Unburt fuel is getting in to the cats heating it up cherry red. Fix the misfire and see if it goes away.

Afternoon all, Misfire and overheating exhaust manifold where caused by a couple of disconnected vacuum hoses at the right rear side of the intake manifold just a few inches past where the MAS hose connects into the manifold. One hose had a good snug fit, but the other (see attached picture) was really spun-gee and appeared not to make a real good seal. On this L shaped connector two red (approx 1/8") hard lines connect into the side and the 3/8" opening attaches to the intake manifold. Anyone knows what it is called and possibly what the part number may be? Thanks in advance. A

was gonna say, red ehaust manifold means running lean. Yes, vacuum leak is a possibility. I would go to a junk yard for this or ask a ford dealer.
