Replace the spark plug wires.
Also, be on the lookout for something that could cause a lean condition such as vacuum leaks and fuel flow restrictions.
Well i am gonna guess you have bad spark plug wire boots, i mean high electrical charge goes thru the plug each time it fires , but glowing ?
If it is glowing red it is partially clogged or the engine is running rich.
Your 2000 Nissan Maxima has a 3.0 liter V6 engine , so it has ( 6 ) engine cylinders It sounds like there is a problem with the # 5 engine cylinder , perhaps an engine cylinder misfire ?
I have been running mine on a 50:1 ratio for a few years now, and have never had a problem
If the check engine light is flashing off and on when the engine is running that means an engine cylinder(s) misfire has been detected . You need to have the vehicle scanned for any trouble codes to help diagnose and then repair the problem
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.
1999 Toyota camery 4 cyl leaks oil when engine running
The issue here sounds like it's the master cylinder failing. It is not retaining pressure when the engine is running. The reason they feel fine when the engine is not running is because the failing master cylinder is not getting power, and in essence is being bypassed.
Operating temperature with a good thermostat will be between 180 and 200 degrees. The ideal running temperature on a 6 cylinder engine is about 196 degrees Fahrenheit.
Get behind the exterior of the car and look, if there's a "V6" stamping at the near bottom right of the trunk lid, it's running on the 3.0 liter 6 cylinder engine (Engine model: 1MZ-FE). If not, it should be running on the standard 2.2 liter 4 cylinder engine (Engine model: 5S-FE).

The engine could be running rough for several reasons. If possible, run computer codes to see if a problem show up. Check the spark plugs for consistent color and wear. If one looks different then there is a problem with the system for that cylinder.
