Accelerator got stuck while passing a truck.

Take extra caution while performing dirve cycles on public roadways. Drive cycles can be difficult to follow under normal driving conditions. Begin by: - Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear defroster on. - Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. - Hold at a steady speed of 55 mph for three minutes. - Decelerate (coast down) to 20 mph without braking or depressing the clutch. - Accelerate back to 55 to 60 mph at ¾ throttle. - Hold at a steady speed of 55 to 60 mph for five minutes. - Decelerate (coast down) to a stop without braking. If all other emissions systems are functioning properly, completing the drive cycle above will set the "readiness flags" required to pass the smog check. It will not hurt to perform the drive cycle 2 or 3 times before the smog test.

If you take your car to smog check station and they talk about drive cycle,that means you need to drive you car on the street at speed of 25 to 35 mph then take it to the freeway and accelerate to get the speed of the rest cars and drive you car at 55 to 65 mph then take it down to the street again and drive a little more the turn it off, this is what the mechanics call drive cycle after this the car if everything is right I mean if there is no any damaged sensor the onboard computer get all the info from the sensors and is ready to the test

Your mechanics is correct.. but that's the short verion!

It's called a drive cycle, drive cycles can be difficult to follow under normal driving conditions. Begin by:
- Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear defroster on.
- Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle.. under 3,000 rpm
- Hold at a steady speed of 55-60 mph for 3 minutes.
- Decelerate (coast down) to 20 mph WITHOUT braking OR depressing the clutch.
- Accelerate back to 55 to 60 mph at ¾ throttle.. under 4,000 rpm
- Hold at a steady speed of 55 to 60 mph for 5 minutes.
- Decelerate (coast down) to a stop without braking.
If all other emissions systems are functioning properly, completing the drive cycle above will set the "readiness flags" required to pass the inspection. BTW, It will not hurt to perform the drive cycle 2 or 3 times before the inspection.

1. The testing has to start with the vehicle under 122 degrees F. Start the engine and idle for 2.5 minutes in Drive (auto) Neutral (MAN) A/C and rear defogger ON.

2. A/C OFF, accelerate to 55 MPH at 1/2 throttle and then 3 minutes of steady state cruise at 55 MPH.

3. Clutch engaged (MAN) no braking decelerate to 20 MPH.

4. Accelerate to 55-60 MPH at 3/4 throttle and 5 minutes of steady state cruise at 55-60 MPH.

5. Decelerate, no braking to end the drive cycle.

In some cases the Powertrain Control Module (PCM) will go into a logic lock not letting the readiness monitors run. Removing the battery cables and touching the two together will normally take care of the logic lock condition.

REbalance tires.

have the tires re-balanced and the front end aligned

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, fuel 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

You have to re-set the obd via using Nissan's approved drive-cycle which is;

1. Start the engine when the engine coolant

temperature gauge needle points to C. Allow

the engine to idle until the gauge needle

points between the C and H (normal operating

temperature).

2. Accelerate the vehicle to 55 MPH (88

km/h), then quickly release the accelerator

pedal completely and keep it released for at

least 6 seconds.

3. Quickly depress the accelerator pedal for a

moment, then drive the vehicle at a speed

of 53 to 60 MPH (86 to 96 km/h) for at least

5 minutes.

4. Stop the vehicle.

5. Accelerate the vehicle to 35 MPH (55 km/h)

and maintain the speed for 20 seconds.

6. Repeat steps 4 through 5 at least 3 times.

7. Accelerate the vehicle to 55 MPH (88 km/h)

and maintain the speed for at least 3 minutes.

8. Stop the vehicle and turn the engine off.

9. Repeat steps 1 through 8 at least one more

time.

If step 1 through 7 is interrupted, repeat the

preceding step. Any safe driving mode is acceptable

between steps. Do not stop the engine

until step 7 is completed. If you cannot or

do not want to perform the driving pattern, a
NISSAN dealer can conduct it for you.

How does it perform acceleration wise up to 55 mph? If good, then I'd have exhaust checked for restriction as well, as in plugged catalytic converter.

it sounds to me like the speedo cable is ready to break i am not familiar with your car model but take it to a garage let me know how you get on
