Question about 1997 Plymouth Neon
TOOK MY 97 PLYMOUTH NEON TO EMISSIONS, AND IT READ NOT READY. THEY TOLD ME IT NEEDED THE DRIVE CYCLE.
A drive cycle is a test that the on board computer performs while you drive the car to prove out all the systems on the car that control tailpipe emissions, if it finds a problem it will trigger a check engine light and and the drive cycle will not complete. The correct name of this is the "OBD2 ELECTRONIC ENGINE CONTROL DRIVE CYCLE TEST". "OBD2" is short for On Board Diagnostics generation 2. The test is just driving the car at various speeds, stop and go traffic and idle time, make sure you have at least 5 gallons of gas in the tank as well. Many folks disconnect the battery to clear a Check Engine light when a smog is due, this resets the computer (known as the PCM) and then you must complete a OBD2 drive cycle, which of course will turn the Check Engine light back on.

There are several vacuum hoses on your Neon.
You need to be specific.
Is it as big as your finger or small a a pencil?
front or back of the engine?
Top or bottom, etc...?
When you open the hood, thee is or should be an Emissions hose routing sticker stuck to the underside of the hood.
If not, find another Neon someowhee and ask to see the sticker or go to the dealer to maybe get one..or...look online for one by Googling it in IMAGES.

Sounds like a timing belt has broken. If you are lucky it has not done more damage. Best to hook up a code reader and see if it is reporting missing cam sensor. If it is, the timing belt is broken.

A service technician will
turn off the dashboard "check engine" light after most repairs. This
resets the vehicle's emission system components to "not ready". The
status remains "not ready" until the vehicle's computer has had adequate
time to review the repaired component. This happens after the vehicle
is driven for a period of time established by the manufacturer.
If the vehicle's emissions system status is "not ready" when it is presented at the E-Check station during the initial test cycle,
a tailpipe emissions test may be conducted. If the vehicle is
transferred to another test type, the vehicle must remain on the
different test track until the vehicle passes the emissions test or
receives a waiver. For example, if the vehicle undergoes an OBD II test
and fails, it cannot be downgraded to a tailpipe test on a re-test; the
vehicle must pass the OBD II test.
For initial and subsequent tests, if a dashboard light is on when the vehicle is presented at the E-Check station, the vehicle will fail the test.
How can the vehicle status be made ready?
When a vehicle is driven through its normal drive cycle, the computer reviews the emission control
system and if the vehicle was properly repaired, the system resets itself to ready. A normal drive
cycle includes operation at both cruising speeds and in stop-and-go traffic for up to a couple
weeks. This process should be followed before bringing the vehicle in to be tested.
