Tha may be fuel filter from fuel pump or fuel filter outside of gas tank or the car injectors
There a number of things depending on the age of the engine. The sparkplugs of an older engine could be poorly gapped, fouled or just need to be replaced. The problem could also be the distributor cap could also be the problem. In a newer car the problem could be injecters or any number of sensers. In any car the problem could be wires.
Try getting the PCV pipe replaced. Mine had a problem with it conking-out at stops and on turns and that turned-out to be the problem. It could also be a vacuum leak.
Since your truck is new, there should not be a problem. Where a problem could happen is if the engine was running poorly on the opposite bank the computer could not make corrections. I assume you are out of warranty also.
If your toilet is still running after the water has been turned off, it could be due to a faulty flapper valve or a problem with the fill valve. These parts may need to be replaced to stop the running water.
Your civic could be running too rich because you used bad gasoline. It could also be running rich if a spark plug needs replaced.
Have you checked the daytime running light module?
It could be either a bad water pump or a clogged hose or a bad heater core or it could be a clogged or bad radiator.
The statement "A poorly running engine may be caused by having too much fuel in the combustion chamber" is not true. Too much fuel in the combustion chamber can actually cause the engine to run rich, leading to issues such as rough idle, decreased fuel efficiency, and increased emissions.
Check for bad ground
Interesting?? I had my starter and battery replaced on my 2002 Saturn VUE and within a few months my low beams ands daytime running lights went out. Dealer says the post in the fuse block is burnt and the entire block needs to be replaced at a cost of over $600.
The belt breaking would be the problem. Investigate why it broke.
could be the regulator
