1997 Oldsmobile Achieva - check engine light is on and car is running sluggishly...brand new motor installed 6 weeks ago.


What speed are you going when it chugs?
It could be as simple as a bad spark plug or a spark plug wire/boot grounding out.
When spark plug boots get old, the rubber cracks and lets voltage arc out the side and to the engine instead of through the plug.
This will be most noticeable when trying to maintain a speed of over 40 mph, or under mild acceleration.
The reason for being noticeable at this speed/acceleration level is that the transmission torque converter will be locked, transferring the vibration from any engine miss straight through to the wheels.

I have a Jetta TDI 1993 Model and I have a problem, while driving the I get no response from the accelerator pedal, the car seems to idle but there is no accelerating power. If turn the engine off and on...


Go back to that VW dealer and complain. I'm sure you payed plenty, and I know in my shop, if a customer's car is not repaired to their satisfaction, I want to know, and make it right. Sometimes parts can be bad right out of the box, and sometimes problems are misdiagnosed. Go back, but don't agree to pay for anything untill you get a satisfactory explanation. Good luck.

2001 Ford F650 with 7.2 Cat deisel acceleration problem


Check your TPS Throttle positioning sensor. Sounds like it has a dead spot in it or it is failing. May also be a wiring harness issue or loose connection at TPS too! If its intermittent then it will soon go out completely. It should be located on your fuel pedal. Remove it and check it with an ohm meter. Check resistance all the way thru from 0-100 percent. When it is not working it should do nothing and show no resistance. When it is working the resistance value will increase and or decrease as you turn the sensor.

The wrench light is a warning light for the transmission or the electronic throttle control .All new vehicle's have electronic throttle control , there are position sensor's in the APP an in the throttle body an they ware out . It's your responsibility to keep it maintained . Not just to jiffy lube !To the Dealer to have diagnostic's run on the electronics. Accelerator Pedal Position Sensor vs. Throttle Position Sensor

I have a 2001 nissan pathfinder 4w. The OBD system-readiness status: Says catalytic converters, NOT READY; oxygen sensors, NOT READY; evaporative system, NOT READY. So did not pass inspection, I was told...


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.
