Check and make sure all cylinder are firing, the reason it's glowing red is because engine is running very rich, and bruning the gas in your exhaust system, and not in your cylinders, to much raw gas is going through your exhaust system.

1992 geo prizm start but won't run we have changed the fuel filter fuel pump distributor cap and rotary button coil pack battery and alternator plugs and wires the catalytic converter was glowing red


Sounds like the cat or muffler is plugged. If there is an 02 senor ahead of the cat or muffler take it out and see if the car will start, it will run rough but if it starts one of them is plugged and it most likely is the catalytic converter in the exhaust system.

1998 Lincoln town car run rich in left side only I replace intenc gasket, spark plug, sthil chek engine on


I think it could be a bad converter or a coil pack getting weak . I've had both issues on the 4.6 and the 5.4 ....to check the converter run it hard when it is up to temperature ( best to do it when it close to dark) pull over look under the car and see if one looks to be glowing red if so it is clogged. Coil packs are not cheap and hard to narrow down which one is bad but go to rock auto.com and you can all 8 for the price of 3 them .
When posting on here if you can inform us of the codes that was pulled it would be helpful.

2002 olds bravada exauste manifold glowing red hot


The exhaust system could be blocked between the engine and the tail pipe. The fuel mixture could be too rich or too lean.
Is the check engine light on ?
Can you rev the engine up in park ?

I have a 2000 ford ranger 3.0 with a po353 coded


well sounds like you may have a few problems but we have to start with what we know is going on. The P0353 is a Ignition Coil Primary/Secondary fault. Check the wiring to the coil pack and see if all looks ok, if so then probably need to repalce the coil pack and that should remove the p0353 fault. The Glowing Converter could be caused as a side effect of this fault as the coild is not properly firing the spark plugs which is causing all the symptoms.
Hope this answers some of your questions

My 1985 mazda rx 7 1.1 gets glowing hot where exhust comes out of the motor , replaced exhust pipe and muffler but didn't help have any suggestions


Hi,
Check the ignition timing.
Make sure the fuel you are using is specified for engine use.
Last one will be to check the catalytic converter if it still open.

Hope that helps!

Ok odds are you just need a routine tune up. Plugs, fuel filter, air filter. Now this engine uses coil packs i think, so you wont have normal plug wires. The coil packs are individual and sit directly on the plugs. So it is possible you have a bad coil pack. These engines were known to have this problem in excess. So try the cheap fixes first. plugs, fuel filter...these two is the best two to try first.. The air filter wont cause a bad miss unless it is completely dobbed up. so just for your own good to change the air filter.Now if neither the plugs or fuel filter fixes this car try this. Each coil pack will have an individual plug on top of them. So listen closely to your engine. Unplug each coil pack one at a time, Now evry time you unhook a plug the engine should miss, so unplug one at a time, and if the engine does miss they are working properly. Now if you unhook one of these and there is no change in the idle of your engine, my friend you have found the problem. All you have to do if you find one that does not change the engine idle, you just go buy a coil pack and replace it. This should fix you right up
