The work you have already done should have cleared up a misfire.As one plug is still sooty,then you either have too much fuel in that cylinder,probably a faulty injector(if it's a multi-point type),or not enough air.If there is a hydraulic tappet fault,the inlet valve may not be opening enough. A compression check and a session on a diagnostic computer, should confirm one or the other to eliminate guesswork and unneccessary expense.
Probably have a misfire or lean fuel mix NELSON
If the check engine light is flashing when the engine is running , that indicates that an ignition misfire has been detected
If the check engine light is flashing with the engine running , that means a spark plug misfire has been detected
Daphne was running from Apollo, and she was running out of breath. She prayed to her father and he changed her into a laurel tree. Thus, why we see Apollo with a laurel crown.
If your check engine light is blinking that means an ignition misfire has been detected
it was running fine and then it started popping thru the tbi and wouldnt run very well had no power
You can lose about 5 pounds a week running 24 miles. This also depends if you have changed your diet and what you have changed your diet to.
because it sucks!
My idle was running rough and slight loss of power (5 cylinder engine). The power loss is more noticeable on cars with less cylinders.
The converter is clogged or the engine is running way to rich or has a misfire.
By running an object with an opposing force into it.
Isuzu uses the spark plug as a sensor of the burn efficiency inside the cylinder of the engine. Use of the wrong brand plug can cause this misfire code in a good running engine. Otherwise perform tune up to repair misfire
there are many common problems with ford trucks 4.6 and 5.4, usually it will be one of two things. A misfire or a vacuum leak
I recently bought a 94' GT...which at the beginning would run but would not idle...and when we did some work on it and got it somewhat stay running...we drove it and it misfired. We were looking for a cheap fix because at the time we hadn't bought it yet. So we changed the spark plugs...but that wasnt the problem. So the next step we changed the Ignition wires and it purred like a kitten. the problem was that the wires had never been changed since the car was manufactured and were getting worn out.
0303 Cylinder 3 Misfire Detected Could be a bad plug or plug wire; or an injector problem. Is it running rough? If it sounds smooth, it could be a transient condition. Such as driving on rough roads or lugging the engine, however rough roads/lugging will unlikely set a misfire code with an automatic transmission. I'd give the light several days and see if it goes out. If it's running a bit rough and it's time for plugs and wires anyway you may go ahead and do replace them. Once it's running smoothly, the light will go out soon--three consecutive ignition cycles without a fault. The way it sets a misfire code is the computer checks the crank position sensor every 100 revolutions for any deceleration that a misfire would cause. If it discovers deceleration, it looks at the cam position sensor in order to identify the cylinder. Therefore the PCM may not detect a light misfire right away. If it detects a severe misfire, it will flash the MIL, since a severe misfire could damage the catalytic converter, and disable the lock up torque converter clutch momentarily to rule out the rough road possibility. Since this code is not set by an actual lack of spark, just unexpected engine deceleration, any action that jostles the engine will be read as a misfire.
o2 sensor out of range, misfire if running rough, too lean injector , fuel filter???
If the check engine light is flashing on and off with the engine running , that means that an engine cylinder misfire has been detected
By energy conversion. For example heat can be changed into kinetic energy by running a turbine to move a vehicle.
When 1990 Honda is running cooling fan does not come on but comes on when engine is off and I thermostat and temperature switch changed?"
Coil packs are known to failiure on these that would be my first line of investigation.
the RV is running bad with spark plugs black
it is because it is running on 5 cylenders or 3 cylinders depending on the motor
If the check engine light is flashing every second or so with the engine running that means an engine cylinder misfire has been detected
