I have a 93 Honda Accord SE. The seals around the spark plugs were leaking and soaked the spark plug wires. This made the engine shake and feel like turning off. I have replace the spark plug seals and spark plug wires and this seemed to help. I was told that the map sensor also need to be replaced otherwise it would begin to shake again. Is this true? Does anyone know if what I am told is correct? I thought that the map sensor only controlled the amount of air that goes into the engine.

The spark plug seals are part of a kit for a valve cover seal replacement. The ones from Honda are the best. A MAP sensor may be the proble but I doubt it. If it is bad the engine will run very rich. Let me know

If the map sensor gets bad it will usually kick a flag up in the computer and trip the check engine light. If the car seems fine after what you did, don't worry about the map sensor.

Suggested Repair

If the engine runs fine after replacing the valve cover spark plug seals and plug wires, leave the MAP sensor alone. Replace it only if the engine runs very rich or a check engine light and code appear. Prefer Honda valve cover gasket seals.

Conversation Summary

The owner of a 1993 Honda Accord SE reported engine shake that felt like the engine was shutting off after leaking spark plug seals soaked the plug wires. Replacing the seals and wires helped. Experts said a MAP sensor is unlikely to be the cause if there is no check engine light and the car now runs fine; a failed MAP sensor typically makes the engine run rich and sets a code.
