Yes, bad gas can cause engine misfiring. Contaminated or low-quality fuel may lead to improper combustion, resulting in uneven engine performance and misfires. Additionally, water or debris in the fuel can disrupt the fuel-air mixture, further exacerbating the issue. Regularly using high-quality fuel and maintaining your vehicle can help mitigate these problems.

Does water in the gas cause backfiring?

Water in the gas can cause misfiring in an engine, leading to backfiring. When water is present in the fuel system, it can disrupt the combustion process by preventing the fuel from burning properly, resulting in backfiring as the engine tries to compensate for the imbalance. It is important to address any water contamination in the gas to prevent engine performance issues.


Does bad spark plugs give you rough idle?

Bad spark plugs can indeed cause an engine to idle rough. If any of the spark plugs are misfiring or are not producing enough of a spark to ignite the fuel, then not only will the engine idle roughly, it will alwso waste gas. If may seem as though it is running fine when you are driving however, you still may be wasting gas and your pickup may not be as fast as it should.

2.9L V6 engine in 1992 Ford Ranger that is misfiring?
