SOURCE: Car shaking and vibrating at 55 mph. and does it again at 65-70.

1.You could be right, check the flexdisk and the wheelhub, since you have already check wheel balance,
wheel alignment, and the steering wheel.
2. Have the following check as well;
a) steering linkage assembly for worn out joint parts.
b) propeller shaft (cross bearing, center bearing)
c) engine mount for defects.

SOURCE: 2000 jeep cherokee transmission disengages for

Inside the transmission are items called overrunning clutches or spragues. What they are is pretty much a bearing that only turns in one direction. I'm pretty sure there is one inside the converter as well. If a sprague goes bad, it will suddenly let go and slip, then re-engage. A good transmission shop can usually recognize this on a test drive and additionally can attach a "flight recorder" to the unit to eliminate the possibility of a diagnostic error.
If the problem is in the converter, and no metal or clutch material is found in the transmission itself, you may be able to just replace the converter. However, if there is debris in the pan, the sprague may not have been the first item to fail but has failed due to contamination of another internal part that has failed. Then, a rebuild is in order.
Of course, I'm assuming that the fluid is full and is not burned, and that you looked at that already. Converter sprague is inside the converter and cannot be replaced . Ones found inside the transmission are on the shaft inside and cannot be changed without taking the unit completely apart. Would make no sense to change it without changing the internal clutches as well.!!

SOURCE: 87 toyota pickup 4x4 22ret i have no injector

OK, the computer grounds one of the curciuts on each injector to pulse it.
Interesting information from alldata, the autodata and mitchell and Bosch AFC all show a code 11 as being ECM (B+) that I have, which could be the EFI main relay, fuse, fuse link or wiring (usually one of the wires on the battery terminal have broken off or corroded and lost connection)
Here is the diagram I have for Bosch AFC on Toyota PU, I'm not sue it will be readable compressed for upload but here you are

If the engine seems to run OK at all rev ranges without stalling, then I would look more closely at the transmission or even the brakes. Make sure there is nothing in the air intake system, such as an animal nest. I would expect that brakes, especially the parking brake, could be rusted badly.

check you ignition components to see if they are worn or faulty, this is usually the cheapest part that can cause this problem since your tach runs off the ignition.check fuel filter before fuel pump as this could be clogged and also not as expensive as a pump or oxy sensor. a faulty oxy sensor will set a code.

V6 holden engine on lpg just stops while driving !


If the filter has already been changed, then the pressure regulator, which also acts as the vaporiser, must be suspect. It is equipped with a soleniod valve that shuts of the flow when the engine is not running,or if it thinks its not running.

Engine problem


When it doesn't start can you check if you hear the fuel pump working when you crank the engine? then check if you get sprk on the ht leads as well. It must be eithr a fuel or ignition problem.
