Engine Shaking On A Cold Start

[Hector Castillo]

Hi I'm new to this whole forum world.

But my question is my engine shakes pretty violently on a cold start and when I begin to accelerate it shakes and seems to be have trouble accelerating. Once the engine warms up it goes away completely and it no longer shakes. I resently changed out the spark plug wires and spark plugs and it doesn't seem to have stopped the issue. any ideas as to what it could be? The motor mounts don't seem to be going out nor do the transmission mounts.

I have a 1997 Mustang GT

Take a look at this thread. The first 2 pages have info on figuring out what isn't working in the engine controls.

Good luck.

Yea that was a lot of info about a SHO 5.0. Is there a guide for 4.6 liter Mod?
