Hello;
You probably have a spark plug wire at fault. If it does nt fire, the fuel dumps into the exhaust and then burns, hence the glowing pipe. Definetly needs to be fixed right away. You may also have an injector stuck.
Hope this helps,

What would cause the two exhaust manifold pipes on the passenger side to glow red hot the ones on the driver side does not get red hot 2000 Mitsubishi galant 2 4


Try checking for a restriction in the system. possibly the catalytic converter. are the pipes before the muffler? you can smack your catalytic converter with a dead blow hammer a few times before you start the engine. you will hear a sound similar to breaking glass from inside the converter it's carbon build up. Start the engine and rev it up a little. If it was constricted the carbon you broke loose will blow on out. If nothing is restricted in exhaust you may have a bad exhaust valve on that side.

Engine light on need to replace 02 sensor how do i change it


It depends on which bank. The O2 sensors will be located in the exhaust pipe. If you have 4 banks, there will be 1 and 2 starting closest to the motor and moving toward the cat converter. After passing the cat converter you will have 3 and 4 which lead toward the under side of the motor and toward the back. If you only have 3, or 2, same deal, just count from the motor and follow the exhaust.

02 grand prix 3.8 engine will not go above 3500-3600 rpm. if i try to drive it it barely can get out of first gear because that is the shift point. when it does go into second it will only get up to about...


two things i can think of, 1) a restricked catylitic converter. 2) faulty fuel pump or injectors. check your fuel pressure a the fuel rail to test the pump. a plugged cat. will cause back pressure in the exhaust, if the car is good and warmed up ( at night or very dark place ) look at the "Y" pipe attached to the exhaust manifold, if it glows a dull cherry red replace the converter.
