It could be running lean. Check the fuel filter. It could also be a vacuum leak or the EGR valve. It would probably be a good idea to not run it much until you've worked out the problem. There are quite a few possibilities, and some of them are not very expensive, but if the exhaust manifold is getting that hot you could be damaging your exhaust valves. If the exhaust manifold is glowing, it's not the cat-converter.

Glowing exhaust manifold code says speed sen and lack of power on a 1995 ford ranger xlt 2.3 litter?

I hope you shut the thing down. If your manifold got so hot it glows I would suspect a clogged catalytic converter. The engine code for your speed sensor probably means it or the wires to it where damaged by the heat radiating from your exhaust.

Why does your catilac converter heat up so brigth red it is a 1989 Jeep Cherokee?

I dont quite understand the question, but if it is what i think it is, then the reason a catalytic converter heats up very hot is because it is a component that uses exhaust fumes, and ehaust fumes are hot as they are the end result of an explosion that happened in the engine, therefore heating up its surroundings and making the catalytic converter hot. a catalytic converter glowing red is normal, and even in my 50cc moped (which was new) the catalytic converter glowed red, so for one in a car engine, that doesnt surprise me (far more exhaust fumes).

What will cause the driver side catalytic converter on a 1997 Crown Victoria to turn glowing red?

It is clogged or you have a miss on the driver side bank of the engine which is causing raw fuel to be dumped into the converter where it is burning. If you find your engine is running fine and has no miss then the converter is clogged.

Exhaust pipe glowing red in 2001 kia sportage?

Timing is off, misfiring spark plug, or overly-rich fuel/air mixture. This will ruin you catalytic converter.

Why does your catalytic converter get cherry red?

It is glowing red because it is plugged up and the metal is getting hot. It is a serious fire hazard, don't drive the vehicle until you have it replaced.

What would cause a1991mercury capri xr2 to stall after it warms up runs for about 10 min and stalls wont start till it sits for a while?

most likely your catalytic converter is clogged. if u warm it up at nite and look under the car and part of the muffler system is glowing red it is usually the catalytic converter and it will have to be replaced.

catalytic converter is probably clogged

Your car acts like it is missing and has no power when in drive could it be the catalytic converter?

highly unlikely, but to check for sure, drive the vehicle for about 15 to 20 min, put it in park and let it keep running, get down and look at the cat converter, if it is glowing red, it needs to be replaced

Why will catalytic converter turn red when car is running new Transmission was just installed?

When traveling home at night from a weekend camping trip, my wife noticed something glowing under the truck. It turned out to be my catalytic converter. My truck had been running poorly and I barely made it home. It turned out that one of my spark plug wires was bad (burned on the exhaust manifold) and was not firing properly. This caused unburned fuel mixture that was not burned in the cylinder to enter the converter where it would ignite and create the high temperatures, causing the converter to glow bright orange. I would say unburned fuel mixture entering your converter is causing the converter to overheat. A bad spark plug wire is only one of several causes of unburned gas. Others could be failing spark plug, stuck carburetor float, etc. Hope this helps.Magdude1ANSWER XXXXXXXXXXXXXXXXXXXXXXIt is possible but highly unlikely as a catalytic converter should NEVER go bad unless something causes it. If you have a check engine light "ON" then I would have someone with the knowledge and equipment to diagnosis it for you. It will save you alot of money. Either a very rich or lean condition will cause a converter to glow red and seem stopped up.jd1709

Red hot exhaust manifold 92 Camaro?

If it's glowing red you have a vaccum leak someplace, probably in the intake manifold or the engine is running lean on fuel or possibly too rich as the unburnt fuel is burning in the exhaust.

What would cause the engine to spuder when you push on gas and die its a 88 thunderbird with fuel injection. it will power at all?

There are multiple possible reasons: Dirty gasoline Clogged gasoline filter Bad sensors Disconnected or broken vacuum lines Disconnected or broken electrical connections Bad catalytic converter Dirty/clogged/leaking fuel injectors I would start by trouble-shooting the catalytic converter. If the car runs at idle but dies during acceleration, a failed catalytic converter could plug the exhaust: less pressure at idle lets enough exhaust through to let the engine run; more pressure on acceleration forces catalyst pieces to clog the muffler, or gases cannot get past restrictions. Look at the converter (it is inline with the exhaust pipes) and see if there is heat discoloration. At night, see if it is glowing red from excessive heat. Another clue is if you hear a rattling sound coming from it, meaning that it is broken. Take it to a muffler shop for confirmation.

How hot is a running car engine?

Depends on which part. The exhust manifold can be glowing red, while the most of the engine should be slightly below the boiling point of water.

Why is the back converter is glowing red after changing both O2 sensors on a 2000 ford explorer xlt v6?

A catalytic converter will rarely fail without a problem or malfunction occurring somewhere in the emission system in front of the converter. It is important to determine what caused the converter to fail, so that the problem can be fixed and to prevent a recurrence of the failure. The converter is super-heated due to a raw fuel condition in the exhaust flow. The excess unburned fuel ignited when it struck the hot ceramic catalyst and drove the temperature far above the normal operating condition of the converter. The ceramic catalyst is unable to with stand the extremely high temperature and begins to melt. The ceramic collapses and the converter is destroyed. The melted ceramic may block the exhaust flow and cause additional damage to the engine. A converter glowing red-hot or evidence of heat discoloration confirm this situation.The too-rich condition that led to this converter meltdown could be the result of a number of malfunctions including faulty oxygen sensor, an incorrect fuel mixture, worn spark plugs or plug wires, a faulty check valve, incorrect ignition timing, sticking float, faulty fuel injectors, a failed fuel pressure regulator or other ignition malfunctions. An oxygen sensor failure can lead to incorrect readings of exhaust gasses. The faulty sensor can cause a too-rich or too-lean condition. Too rich and the catalyst can melt down. Too lean and the converter is unable to convert the hydrocarbons into safe elements and may not pass a state inspection.

After you changed the plugs the check engine light blinks and when you tried to drive off it seems as though it was not getting any gas and the manafold was turning red as fire?

1. The flashing check engine means DO NOT DRIVE AT ALL and must be turned of by a scan tool 2. A glowing manifold means DO NOT DRIVE AT ALL 3. You probably installed the wires incorrectly check the firing order per the repair manual start the car and put your hand by the tail pipe and have someone give it gas there should be alot of pressure leaving the exhaust if not replace catalytic converter

What would cause a headache when exhaust fumes enter the cabin when the heater is turned on a 1996 Buick Regal how can this be fixed?

Carbon monoxide is an odorless gas. It would be my guess that the fumes are entering all the time with the fan helping to circulate. My guess is that the catalytic converter is clogged. The indication of this is poor power, terrible fuel economy, and if you look under the car at night, a glowing red converter. VBD I don't know how to fix it but get it fixed because it sounds as though you are getting carbon monoxide poisoning which can kill.

Your valve timing is off The o2 sensor is not reading properly causing the system to go very lean.
