This sound like a secondary ignition issue, try doing a complete tue up if it persists then try looking at the egr as sometimes they will stick open & cause the same problems.

The most common source of a missfire and shake like you discribe in the 4.6 V8 is the spark plug boots shorting to the cylinder head, replace the plug wires.

Why does my truck shut off when put in gear, does not idle runs normal

Hi Im AL the owner of Big As Auto Repair.

Most likely the "IDLE SPEED MOTOR" is stuck or not working at all. Here's what I want you to do. Start the engine and let it idle, then take something like a small hammer and tap on the idle speed motor several times, then put it in drive and see if it dies. If it keeps running normal, then replace the Idle Speed Motor. Hope this helps and please visit my auto-repair-website here:

I have a 2003 ford mustang gt wipers stopped working replaced relay and fuse and still nothing is there something i am missing. I was told that it was the connestion under the right front fender but idk...

try tapping the wiper motor, with it turned on, with a hammer if it starts the motor is worn and needs replacing. you can try attaching a separate ground wire to the wiper motor if it runs then the motor has lost its ground and you can run it this way.

96 nissan P/U 2WD, feels like missing cyclinder should I replace EGR value?

Disable the EGR valve and test. If issue is resolved you have 3 plugged EGR ports and all the EGR flow is being routed to # 4 cylinder resulting in misfire or the EGR valve is sticking open at times though you probably would not feel a misfire except @ idle & take-off.

The engine on my mustang v6 2002 idles fast then slows down, feels like the car lunges, could it be the idle sensor?

This can be caused from a vacuum leak or yes the idle sensor, this part is called an idle air control valve, also try checking for vacuum leaks and then clean the throtlebody good, use throtlebody cleaner and an old tooth brush to clean, sometimes they are just dirty.
