What causes intermittent misfires in a fuel tank?
Intermittent misfires are often caused by a weak spark or a lean fuel mixture. That piece of knowledge may not tell you what is causing the misfire, but it should help you plot a diagnostic course in one of two directions. Random misfires are another type of misfire that can be hard to nail down.

What happens when an engine is not firing properly?
When one or more cylinder is not firing properly, the engine will become unbalanced, and this can cause heavy vibrations inside your cabin on acceleration or at idle.
What happens when the throttle body goes bad?
Nowadays there is an electric system that’s far more efficient than the old ways but it can still have issues. When a TPS goes bad, then the car’s throttle body won’t function properly. It could either stay shut or it won’t close properly which is a severe issue. If it stays shut then your engine is not going receive air and it won’t start.
Why does my car misfire at full throttle?
This prevents pre-ignition misfiring and it does not function at full throttle. A stuck/ inoperative EGR valve can contribute to the problem. Also, if any EGR tubes or passages are clogged with carbon due to age and mileage, the EGR “loop” will not function.

When does the misfire of an engine go away?
For the combustion to be successful, the mixture needs a specific proportion of fuel for the amount of air entering the engine. Otherwise, you will notice the cylinder misfire while your engine is idling. But when you’re driving at faster speeds, the symptoms of the misfire will go away.
Can a mechanical problem cause an engine to misfire?
Many people also don’t realize that an engine mechanical problem can cause a misfire. Each cylinder inside the engine contains a piston that must compress the air/fuel mixture for complete combustion. And when the piston is moving upward, the cylinder must remain completely sealed off to create adequate compression.
