Engine shuts down on deceleration

1999 Cadillac Catera 145K miles engine shuts down after appox 30min driving at 65-75 mph during a deceleration for exit or turn.
Why does the engine shut down?
Restart is possible after 10 or 15 min, during this time the engine will crank without any attempt to start.
After restart, in Drive, the trans slips, turn off engine, restart, recyle the gear selector all is fine, for 30 or so minutes.
Any root causes?

    crank position sensor problem - all sorts of dash lights will activate with this sensor intermittent.

    to find the problem have the DTC scanned with a better than parts store scanner.

    in this case there were 4 codes, 3 pointing to the position sensor and the 4th showing a light bulb isn't working.

    replaced the crank position sensor all is well.

Crankshaft position sensor is the most likely issue.

Well 145K is alot of miles, catera's are not that reliable especially after 100K. It sounds like you could have multiple issues but take it to a mechanic asap before it becomes unfixable.

What is the drive cycle for a 1999 vw jetta


The drive cycle is as follows
For all OBD2 VW's

OBD-II Drive Cycle Stages
The OBD-II Drive Cycle is an eight-stage course, as illustrated in the
chart on page 3. An explanation of each step is provided below.
Stage 1: Cold Start-The ECM determines the presence of a cold start
by comparing the engine coolant temperature to the ambient air
temperature during startup. The engine is considered cold when:
• Engine coolant temperature is below 122°F (50°C).
• Engine coolant and intake air temperatures are within 11°F (6°C) of
each other at startup.
During this period, the O2S heater, misfire, AIR, fuel system, and EVAP
monitors run.

Stage 2: Idle 2½ Minutes-Turn the air conditioning (A/C) and
headlights on to help the misfire monitor-the additional electrical loads
help even out combustion pulses. During this period, the O2S heater,
AIR, EVAP, misfire, and possibly fuel system (if operating in closed loop)
monitors run.

Stage 3: Accelerate-Prior to accelerating, turn off the A/C and
headlights (if possible). Open the throttle halfway until you reach
55 MPH (89 KPH). During acceleration, the misfire, fuel system, and
EVAP monitors run.

Stage 4: Steady State Cruise-During this portion of the cycle, the
O2S, AIR, EGR, EVAP, misfire, and fuel system monitors run.

Stage 5: Decelerate-Gradually coast down without applying the
brakes. Also, on manual transmission vehicles, remain in high gear and
do not press the clutch. During this period, the EGR, EVAP, and fuel
system monitors run.

Stage 6: Accelerate-Apply ¾ throttle until reaching 60 MPH (97 KPH).
During acceleration, the misfire, fuel system, and EVAP monitors run.

Stage 7: Steady State Cruise-During this period, the CAT, O2S, AIR,
EGR, EVAP, misfire, and fuel system monitors run.

Stage 8: Decelerate-Gradually coast down without applying the
brakes. Also, on manual transmission vehicles, remain in high gear and
do not press the clutch. During this portion of the Drive Cycle, the EGR,
EVAP, and fuel system monitors run.

You can try this a couple times, but if it doesn't work you should go to a VW specialty shop like the dealer or a shop that does mostly European cars and they can use the scan tool to force the car through readiness.

Not Ready for Smog test


it is not how many miles but the type of driving.

here is a OBD2 drive cycle test.

Generic OBD II "Drive Cycle" Most OBD II ("On-Board Diagnostics II") diagnostic monitors will run at some time during normal operation of the vehicle.
However, to satisy all of the different Trip enable criteria and run all of the OBD II diagnostic monitors, the vehicle must be driven under a variety of conditions. The following drive cycle will (theoretically) allow all monitors to run on (??) vehicle. (Note: Drive cycle specifics vary by vehicle!)
  1. Ensure that the fuel tank is between 1/4 and 3/4 full.
  2. Start cold (below 86°F /30°C) and warm up until engine coolant temperature is at least 160° F (typically requires at least one minute; up to 3 minutes).
  3. Accelerate to 40-55 MPH at 25% throttle and maintain speed for five minutes.
  4. Decelerate without using the brake (coast down) to 20 MPH or less, then stop the vehicle. Allow the engine to idle for 10 seconds, turn the key off, and wait one minute.
  5. Restart and accelerate to 40-55 MPH at 25% throttle and maintain speed for two minutes.
  6. Decelerate with using the brake [or the clutch!] by coasting down to 20 MPH or less, then stop the vehicle. Allow the engine to idle for 10 seconds, turn the key off, and wait one minute.

Reset computer in doege stratus wont pass inspection drove 50 miles and computer still didnt reset help


U have to operate the engine at all kinds of diff speeds and drive modes, it is called a OBDII drive cycle, here is how u do one.
1. As soon as the engine starts, idle the engine in drive for two and a half minutes with the A/C and rear defrost on. OBDII checks oxygen sensor heater circuits, air pump and EVAP purge.

2. Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. OBDII checks for ignition misfire, fuel2_bing.gif trim and canister purge.

3. Hold at a steady state speed of 55 mph for three minutes.

OBDII monitors EGR, air pump, O2 sensors and canister purge.

4. Decelerate (coast down) to 20 mph without braking or depressing the clutch. OBDII checks EGR and purge functions.

5. Accelerate back to 55 to 60 mph at half throttle. OBDII checks misfire, fuel trim and purge again.

6. Hold at a steady speed of 55 to 60 mph for five minutes.

OBDII monitors catalytic converter efficiency, misfire, EGR, fuel trim, oxygen sensors and purge functions.

7. Decelerate (coast down) to a stop without braking. OBDII makes a final check of EGR and canister purge
