Bike misfiring? Vibration not smoothing out when giving it gas, running rich.

Bike misfiring? Vibration not smoothing out when giving it gas, running a bit rich. This is an EFI engine. Not too sure if it's 2 separate issues, one of them being the motor mount(s)?

Check the engine mounts to the frame. these are isolated by rubber and you may have broken one gettin' on it at the light.

SOURCE: 2005 dyna wide glide...fuel injected...have engine

This could be a result from a couple of different things however if your vibration is at idol and has and keeps getting worse it is proably one of the motor mounts. These can very difficult to see so if you remove one there is a thin lip above the rubber and metal bracket and if that is not there then the mount is no good

SOURCE: engine vibration,new motor mounts,and stabilizier,94dwg help!

Ok, that's better. This is an engine that has run well before but now something is wrong.

I could be a magnet on the stator but usually they'll make a loud knocking noise. But one magnet could have come loose and simply moved. The only way to find out is to pull the primary and the stator. It's much easier to do on that bike than it is a Shovelhead in that you do not have to pull the inner primary. If you find this to be the problem and you replace the rotor, make sure you check the rotor for good magnetism. Don't laugh, we installed on a few weeks ago and the alternator would not generate any electricity. Turned out the rotor magnets didn't have enough magnetism. You could tell by holding a screwdriver to the magnets, the new one just didn't hold the screwdriver like it should have. Installed the old rotor, everything was fine. Harley had a problem with a batch of them and they don't know where they're all at so check it out before you install it.

Also, with that many miles on the bike, you need to check the motor mounts, both front and rear. The rubber will seperate from the metal parts of the mount. Check the upper stabilizer link as well. Check the primary chain adjustment as well.

As long as the engine is running properly and not making a noise or missing, this is the only thing I can think of at the moment.

Good Luck with it.
Steve

BTW: I've got a '94 Wide Glide. I love it. Wouldn't trade it for a brand new Softail.

Cylinder 1 misfire detectedrich or lean air/fuel mixture fuel injecter fault and faulty crank shaft sensor


Wow... Thats a lot of diagnostic codes. First... The cyl #1 misfire will cause the Engine to run rich giving you a rich running engine. Therefore the rich lean code. This misfire on cyl #1 can also throw a crankshaft sensor code as it will slow down engine rpm. I would change the spark plug and ignition coil to cyl#1 and have the codes erased and see if that solves the problem. If not, you then need to persue any codes that may reappear.

Blazer is misfiring only in drive while stopped then runs smoothly when accelerated po codes 452 125 are also coming up what is it


Code P 0125 indicates insufficient coolant temp to enter closed loop operation. Most likely cause is either engine is not warming up (stuck thermostat) or more likely bad coolant temp sensor is making computer think engine is not warm and thus sends excess fuel injector pulse making engine run rich. Very common problem which kills gas mileage and may make car run poorly. Easy part to test or just change.

Engine light on and misfiring and want to fix this and get it running smooth


The cylinder misfires cause lean or rich
fuel trim

A constant lean on fuel trim, is a rich condition
driven lean by pcm to correct

If two cylinder are affected & are together or maybe
not ,then smoke the intake for vacuum leaks

A leaking injector is obviously a rich senerio

Converter only works with the O2 Sesnors to report
back the rich or lean to pcm

You need to get rid of the misfires before any fuel control
returns to normal

94 jeep grand cherokee front end vibration


Many things will cause vibrations, especially on 4WD trucks. Causes include: worn ball joints, worn tie rod ends, bent wheels, tires out of balance/shifted belt in tire, worn steering dampener, worn u-joints, worn CV joints, engine problems such as engine misfire, a bad fuel injector clogged fuel filter or injectors, worn ignition parts, etc. I suggest you apply the service brake in gear and give it a lot of throttle (power-brake)to determine if the engine is running smoothly or if it runs rough. Also, with the hood up, you can see the shaking if it occurs. If rough, check everything over and repair as necessary. If smooth, start checking ALL other vehicle systems and repair as necessary.

I have a 2002 honda vtx 1800 will not idle but loads with gas


Check for a blocked airbox vent, sometime we put things under the seat that will cover the airbox inlet which will automatically make the bike run extremely rich and all that needs to be done is to remove the paper or gloves or whatever there is blocking the inlet snorkel. You may also want to check for tight intake valves too. That is classic Honda, tight valves will cause a rich mixture all the time if it is the intake valves making the problem.
Please let me know if this works, if not give me more specific data and I will better assist you.

Acceleration vibration


need to get the carbs synchronized Tom. sounds like you are still getting a rich condition in either/both one and two cylinders resulting in uneven combustion pressures. Getting your carbs sync'd should fix the vibration and the overly rich cylinders ,
