I had the internal ceramic grid in the catalytic converter disintegrate into small pieces and go into the muffler. It would drive about five miles and then the check engine light would come on and loose power. It was a bear to diagnose.

Your 95 ford probe dies when its ran for 10 minutes why?

need more info. does it shut down while driving? shut down on decelleration? acceleration? does it sputter or is it like the key was shut off? is there a loss of power before it happens? does it restart right away or do you have to wait , and if so, how long? is the yellow "check engine" light on: Does it stall every ten minutes until it's fully warmed up?

At what point does it lose power? As you're driving? When you come to a stop? plugged converter

Why does more engine power result in faster acceleration?

you are introducing more gas to the engine, which gives it more fuel to burn, resulting in more power. and engines have a certain rpm that they run best at. each engine has its own sweet spot in rpm.

Calculate the accelaration of car by its engine power in cc and force applied by it?

One cannot "Calculate the accelaration of a car by its engine power in cc" and hence derive the "force applied by it" because, depending on the configuration of the engine varying amounts of horsepower (ie engine power) can be obtained from the same size engine. One would have to have a known amount of "engine power" to apply the "F=ME" formula and from there calculate the acceleration possibilities.

What does jerking and losing power during acceleration mean?

it means there is something wrong with the spark plugs cause they provide the energy for the engine

Does driving with the lights on increase fuel consumption?

(no it uses the energy from the car battery not the energy made by the engine)Yes it does increase consumption because the battery has to be recharged by the power of the engine driving the alternator or the dynamo

Why does your car lose RPM when driving?

If you mean why the difference in RPMs between idling and driving, the difference is due to the engine load; At idle, the engine isn't really doing much other than staying running, but under load (driving) the engine has to put its power out to the drivetrain, hence the symptomatic loss of engine speed (RPMs).

When air condition is on it lessen the acceleration?

Yes, there usually will be a slight loss of acceleration with the ac on. The ac compressor is turned by a belt connected to the crankshaft, causing a parasitic drain of power from the engine. At highway speeds, the effect is negligible, since the engine is turning at a steady rate.

What is the difference between power and torque?

In simple terms, torque gets you moving and power keeps you moving. In other words, your acceleration is dictated by the torque your engine provides and the top speed is limited by the power.
