What you might actually need to do depends on the *specific* problem you're experiencing. Possible issues and solutions could include:
* Engine misfire: This could be due to a variety of problems, including bad spark plugs, ignition coils, fuel injectors, or even a faulty sensor. A diagnostic scan by a mechanic is necessary.
* Low compression: This could indicate worn piston rings, a blown head gasket, or valve issues. This requires a significant engine repair, likely involving disassembly.
* Engine knocking or pinging: This could indicate detonation (pre-ignition) from using the wrong fuel, low-quality fuel, or problems with the ignition timing. It could also signify more serious issues like worn bearings.
* Engine won't start: The problem could range from a dead battery to a more serious engine failure.
In short: If your Dodge van's engine isn't running correctly, you need to diagnose the problem. Don't attempt major engine repairs yourself unless you have significant mechanical expertise. Take it to a qualified mechanic for diagnosis and repair. They will use diagnostic tools and their knowledge to determine the root cause and address it appropriately, which will likely involve far more than just "resetting pistons."
