99 Honda civic: diagnostic..the car started to shake and then die

Resolved Question:

I drive a 99 Honda civic, and I had a diagnostic reading of P0303, but right after I had it read the car started to shake and then die at stop signs or when I start to go? What could it be?

Here`s what you Have;

The scan tool indicates Diagnostic Trouble Code (DTC) P0303: Cylinder 3 misfire detected.

Misfire detection is accomplished by monitoring the crankshaft speed with the crankshaft speed fluctuation (CKF) sensor which is attached to the crankshaft.
If misfiring strong enough to damage the catalyst is detected, the MIL will blink during the time of its occurrence, and DTC P0301, P0302, P0303 or P0304 will be stored. Then, after the misfire has ceased, the MIL will come on.
If misfiring that increases emissions is detected during two consecutive driving cycles, the MIL will come on, and DTC P0301, P0302, P0303 or P0304 will be stored.

NOTE: If some of the DTCs listed below are stored at the same time as a misfire DTC, troubleshoot those DTCs first, then recheck for the misfire DTC.
