The vibration could be caused by regular misfiring of the engine. I'd check for vacuum leaks, failed ignition wiring; check at night for sparks under the hood where they don't belong. If the wiring hasn't been changed since the truck was new, it's probably overdue. Bad wiring can also become sensitive to high ambient moisture too.

Cold choke baffle has 3/16 opening minute I pump accelerator choke thermostat closes primary baffle shut no air to start I force choke open to start why insufficient air to run at high idle?


Your engine probably has an automatic choke device that adjusts automatically with engine temperature. To set the choke when the engine is cold you have to depress the accelerator to the floor and release it completely. You shouldn't have to depress the accelerator again to start the engine, turn the key the engine should start. As the engine begins to warm up it will also begin to initially run faster then it will start to run rough. At this point you have to press the accelerator and release it again. The auto choke mechanism should allow the choke butterfly to open. There may be a number of stops in the system and the choke butterfly will stop again still not fully open and only become fully open when the engine is at operating temperature. Hope this answers you question, Rgs. Bob

Vibration at 80-100k in a 4x4 Ford 350 diesel superduty


Sounds like you need to get your tyres balanced. If the vibration is when you don't touch the brakes only between the 80-100.
If its when you touch the brake pedal and the vibration occures, your disc brakes are warped, either machining or replacement.

I have a 2005 land cruiser. It has a slow acceleration and begins to vibrate from underneath as the acceleration increases. Can you advise please? Thanks


do you hear a loud hissing sound when you take off?
Could be the cat converter.

if not that, I've seen CV axles that caused poor take off and vibration.

let me know what you find.

Why does my 1998 sebring idle fine but sputter badly under load.


Does it use spark plug wires or individual ignition coils for the each plug?. My 98 intrepid uses coils and occasionally I have to change them out cause it would start to miss when normal temperature was achieved. If it uses wires, try replacing them, along with the spark plugs.

2003 ford f 150 4.6 v8 and the idle went from smooth to rough also sputters and sluggish while driving check engine light is flashing.


have the vehicle scanned for error codes at autozone, its free. Post codes for more help....These engines have issues with the COPs (ignition coils-over-plugs) failing prior to 80k miles. When they fail typical problems are: Sputtering under load/acceleration, rough idle, random misfires, random stalling, light or heavy jerking under load (usually at 15-35mph and 45-65mph)..hopefully this helps!!
