    Invest in a fuel pressure gauge. It is a great tool to have in your tool box and you can pick on up at a parts store for about 20 dollars.

I have 1998 ford expedtion runs rough pipes get red hot. took pipes loose. no power still. put new plugs no luck please help!


It takes a lot of heat to make the exhaust pipes get hot enough to glow red. It is a dangerous condition and can lead to a vehicle fire. A clogged catalytic converter or manifold could cause this, but ultimately the heat from the exhaust fumes is not exiting the system properly. Even a clogged tail pipe could cause this. A vandal might have stuck something in the end of the tail pipe.
It is running rough because it cannot push the exhaust out and therefore cannot take in enough air.
Regardless of the cause, have this inspected and the blockage/clog removed repaired and do not continue to drive the vehicle with this condition.

2001 Caravan has red hot catalytic converter and #4 misfire error code.


Engine is way too rich. You will burn that car up. Unburned fuel is getting into the CAT and igniting. Check the injectors.

Random multiple misfire code. Cat gets glowing red hot. Sluggish lack of power/acceleration


Combining the hot cat converter and the missfire code, I would lean toward a fuel problem. Too lean or pressure too low.
If it was an ignition problem the cat would usually not be hot.
If the exhaust was stopped up, you would not usually get the multiple missfire issue. Just lack of power.
It could be a leaking EGR or other vac problem, and a dirty fuel filter too.

My chrysler intrepid 2001 is completely done. I was driving home from work one night and halfway out the driveway it began to knock and then everything just shut off. The car would start again but the gas...


The timing chain has jumped. It starts with the cam sensor unplugged because the ecm sees the camshafts aren't in time with the crankshaft. With the cam sensor unplugged it doesn't know its out of time and it starts. It likely has a bad waterpump which caused the chain to jump. The converters were glowing because when the engine runs with the cam timing off it causes excessive exhaust temps.

My catalyic converter is cherry red


The catalytic converter is the hotest component on a vehicle during operation. I have seen them hot enouigh to glow at night but that was after some hard runs/racing. However, if the vehicle is driven regularly it should not get hot enough to glow. Possible cause would be running to rich "they are designed to burn off excessive fuel"

2000 mercury sable losing power


More than likely you have unburned gas that cause the converter to glow red.This will happen if you have a missfire .Spark plug wires could cause this problem.But one or more of your cylinders is not firing properly :)

The car started running extremely rough all of a sudden the cataletta converter is glowing red somebody told me to pull out the o2 sencers see if the car runs better if the converter was clogged but it...


If your converter is glowing it means that its clogged. You'll have to either replace it or break out the ceramic core. I'd recommend replacing it but this can be costly. To give it a quick fix you'll have to disconnect the converter and use a pry bar to break out the ceramic core, then reinstall the shell.. the down side to this fix is #1 emissions are higher #2 louder #3 may cause a problem with your O2 sensor....and may possibly be illegal
