If you have a manual gear box there are two things that you can check. First is the engine mounts especially the rear one to see if the rubber has broken away. Check all engine mounts for the same problem.. The second is a failing clutch or if you have a cable operated clutch it points to engine mounts. What appears to be happening is when you engage the clutch in first gear the torque reaction of the engine is rolling the gear box away from the clutch actuation arm or lever. The clutch slips ,the engine rolls back ,the clutch engages , the engine rolls and so you have a bad shudder. When you are moving the reaction is less as you move up through the gears . If all is good then have a qualified clutch and brake specialist do a check on the clutch itself.

SOURCE: Engine stalls when shifting into any drive gear.

It sounds like your idle air control valve could be going out on you.  The extra stress from being in gear can cause the car to stall out if the IAC valve isn't opperating properly.  The IAC is attached to the throttle body and is normally held on by two screws.  IAC valves are relatively cheap from AutoZone and easy to replace.  That would be my best guess based on your description.  Good luck and let me know if you have any other questions.  Thanks for an honest rating and for using FixYa!

suggest that you check your transmission fluid post haste please. you may only need to add transmission fluid to your car. also,if you have to add the fluid,where did your fluid leak? check for leaks under your car when parked. you may need transmission fluid and filter change,suggest that you do this with new filter and add lucas transmission treatment to the fluid change also. you'll need to purchase this yourself,unless you have a mechanic in the family that can do it for you.if not i suggest you find a mechanic you trust,then tell him,or,her to add this to your tranny fluid change. also suggest while the mechanics there at the transmission to check the modulator valve on the transmission,and the vacum line that operates it. just a hint. thanks for choosing fixya.com

I just bought this 2001 grand marquis, the problem im having started as a small vibration when the transmission was shifting between 3-4th gear in overdrive up hill well now a few weeks later my car is...

As a test, you can switch the overdrive OFF with a push of a button. The engine will run at higher RPM so test it under 55MPH.

I am thinking about your comment of "One side shaking". This sounds more like a loose wheel or dragging out of round front rotor. Then when you comment about the vibration stopping briefly when accelerating or decelerating, that's a lot like U-joint play. The U-joint has play and tightens at the extreme edge of its mount as it rocks from Torque direction changes.

I would say to have an Alignment shop check the front suspension and driveshaft. These inspections are not something a beginner should do.

2007 Jeep Wrangler Unlimited Sahara

SUBJECT:
Long Crank Time Due To Possible Contact Of Camshaft Sensor To Camshaft Gear
OVERVIEW:
This bulletin involves the replacement of the engine camshaft sensor.
MODELS:
2007 (JK) Wrangler
NOTE: This bulletin applies to vehicles equipped with a 3.8L engine (sales code
EGT).
SYMPTOM/CONDITION:
The customer may experience one of the following conditions:
a). Long engine crank time.
b). Two engine start attempts prior to engine starting.
c). Due to the “TIP Start Feature” on automatic transmission equipped vehicles, once the
ignition key / switch has been released from the “START” position, the starter may stay
engaged for up to 10 seconds while the engine attempts to start.
The above conditions may be due to the position of the camshaft sensor to the camshaft
gear. The sensor spacer gasket may have come loose during engine assembly and
caused the camshaft sensor to be adjusted too close or in contact with the camshaft gear.
DIAGNOSIS:
If the above condition is present perform the Repair Procedure.
PARTS REQUIRED:
Qty. Part No. Description
1 04686353 Sensor, Camshaft

My Tracker shakes like a wet dog when idling!!

You could check to make sure the plug wires are all intact. If they are, try replacing the wires and plugs. It could also be that the idling is set too low. It could be the mapping sensor as well. Also try, Maybe the coil pack is going bad. It will cause the engine to misfire. The can be bought at Auto Zone or Advanced Auto. Some place like that...
