The most likely cause is a dirty fuel filter that starves the engine.
If your car shakes while accelerating check your motor mounts. Then check your transmission.
The warning system on the 1994 model Mercury outboard can be activated by either the low oil sensor, located in the bottom of the oil reservoir, or the overheat sensor, located in the block near the spark plugs. The oil sensor will cause a series of "beeps" while the overheat will sound a continuous tone.
A loss of power on a Toyota Celica GT while accelerating can be a number of things. The timing might be off. The coil pack might be allowing for a misfire. There might also be a bad Oxygen sensor or bad distributor.
If no codes (check engine light) or rpm fluctation first check fuel pressure
The most common cause for a lack of power whilst accelerating is a clogged exhaust system or lack of sufficient fuel being delivered to the engine. Check your catalytic converter if your vehicle has one, and then change your fuel filter and go from there.
AnswerIf you are having problems with power while shifting and accelerating have your fuel censor looked at. You may need egr valve checked .You may need intake decarbonized .You may need mass air flow sensor .
Your Volkswagen Cabrio might lack power and feel restricted while accelerating because it has a clogged fuel filter or clogged air filter. It might also lack power because there is water in the fuel.
could be two things. if it does it while idling or accelerating, then its probably a spark plug not firing. if it only does it while accelerating or under load. then its probably a spark plug wire. either way, as general maintenance its a good idea to replace all the wires and plugs. Clogged catalitic converter will cause it to lose power.
the reason an engine "jerks" is because all of the fuel going into the cylinders are is not completely burning thus causing a loss of power...
Mercury Marine has recommended 87 octane fuel in their outboards. While the engine may well run on a lesser octane fuel, I would personaly err to the side of a higher rated fuel.
Outboard boat motors come in a variety of sizes and are measured in horsepower. The smallest, used to power very small craft are rated at under 5 HP while the largest are 300 HP and above.
