My car shake I thoug it was a bad spark plug didn't see any spark when I took the plug wire so I change it but still no spark what else can it be whe the wires are brand new?

A lot depends on what kind of car it is.

There is an engine miss?

Plugs, wires, coil packs... we need more information.

Provide year, make, model, engine.

Sorry is a 05 ford taurus se v6

DOHC or Vulcan (OHV) engine?

Check/replace the coil pack, if you have the OHV engine. Be sure to use dielectric grease on connections. Fully seat the plug wires in the coil. If the problem persists, focus on the Crankshaft Position Sensor and the PCM (possible bad spark driver). Only use the same Motorcraft spark plugs that originally came in the car. How long has it been since all of the plugs were changed?

It was about 2 moths ago and I have sum experience but not enoug to try what you talking about but thanks I make sure I mention it to the mechanic
