Shake and miss-fire.....have you noticed any other symptoms? I would check spak plugs and hight tension leads for cross/miss fire firstly as this would be the most common cause. Once you are confident that these are not the problem you then have to open the can of worms. Most vehicles produced after 1990 are computer controled. This relies on sensors sending sending information to the computer so that it can deliver the correct spark or fuel mixture at the right time. If a sensor is sending the wrong info the computer sends a faulty adjustment which will cause a miss fire which will cause your vehicle to shake and lose power. The quickest way is to plug an analizer in to check the sensors. If that is not possible for you then more info is needed to give an educated guess at a correct diagnosis

My 2002 Mazda MPV recently developed an engine shake when stop at intersection or driving 45mph or slower. My mechanic scanned and found OS2 code, vacuum leak, replaced the intake hose, reset engine...

You might try another mechanic if this one can't get it fixed. Shaking is usually caused by one or more cylinders mis-firing for whatever reason--usually faulty ignition or fuel injection. Has the engine had recent tune-up? Bad spark plugs/plug wiring are frequent villains. Not sure what an 'OS2' code is. Hope this helps!

I have a 2000 ford expedition. Out of the blue it started sputtering and shaking when I accelerate. Vehicle has144,000 miles.

Sounds like one of the coil over plugs have gone bad. this will cause mis-fire which causes your car to sputter, skip, and shake. It can be changed easily when finding out which one it is. But rather expensive for a simple part $40+ each.

2003 navigator and right around 60mph i get a wicked shake or **** in the car. i think it may be a mis fire on the cylinder but not sure

Had the same problem, if it sputters/jerks around 50-60MPH with your foot slightly on the accelerator, replace all 8 COPs(Ignition coil over plug) and sparkplugs....It will get worst and end up ditching you!! NOTE: Make sure if you replace the sparkplugs, that the you or your mechanic works on the motor COLD and are very careful removing and replacing them. These 5.4L on 97-04 models are known for very little plug threading, therefore ejecting the plug out of the motor. This will result in major engine damage. Hopefully this helps

around 75,000 miles, plus or minus 15,000 or so. when you say shaking, do you mean a rough idle? thats not cause by your transmission per se...

Sounds more like a weak fuel pump, idle controller, or well, theres a bunch of reasons you could have a rough idle.
