How do you reprogram an accelerator pedal?
Operation Procedure
- Make sure that the accelerator pedal is fully released.
- Turn ignition switch “ON” and wait at least 2 seconds.
- Turn ignition switch “OFF” wait at least 10 seconds.
- Turn ignition switch “ON” and wait at least 2 seconds.
- Turn ignition switch “OFF” wait at least 10 seconds.
Can a bad EGR valve cause poor acceleration?
Answer: The EGR could be stuck open. If the engine is fed exhaust fumes continuously, this can overheat the valve, cause poor acceleration. Check the EGR system and see if a bad vacuum solenoid is keeping the valve opened. Check the control circuit as well.
When did General Motors start using EGR valves?
Well the good news is that this is an EGR valve and EGR valve system that is very easy to test and diagnose and this article will walk you thru’ the entire diagnostic/troubleshooting process. General Motors has used different types of electronic EGR valves and this article focuses on the Linear EGR valve from the mid 90’s to the early 2000’s.
How to test the GM EGR valve-Buick, Olds, Olds?
By looking at the base of the EGR valve. To illustrate this, look at photo 3 of 4 and photo 4 of 4 in the image viewer above. The EGR valve in photo 3 of 4 (with the red X) is not covered by this article and is tested differently. The EGR valve in photo 4 of 4 (with the GREEN check mark) is the one covered by this article.
Where are the EGR Jets in the intake manifold?
A more radical design, implemented in a few models, was the replacement of the valve with EGR jets at the bottom of the intake manifold. Some newer high-efficiency engines, for example those with variable valve timing (VVT), don’t even use an EGR system. If playback doesn’t begin shortly, try restarting your device.

What are the symptoms of a bad EGR control solenoid?
One of the first symptoms of a possible problem with the EGR control solenoid is engine performance issues. If the EGR solenoid has any issues, it can cause the finely tuned air fuel ratio to be thrown off. This may result in a decreased power, acceleration, fuel economy, as well as an increase in emissions.

How to change the accelerator pedal release position?
Accelerator Pedal Release Position Learning Procedure. Make sure that the accelerator pedal is fully released. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds.
What happens when your accelerator pedal sensor goes out?
If the accelerator pedal sensor fails, the following fault symptoms may occur: Increased engine idling speed. Vehicle does not respond if the accelerator pedal is pressed. Engine warning light in the cockpit illuminates.
Why is my accelerator not working?
A dirty or clogged fuel filter is another reason for a car not accelerating like it’s supposed to when required to do so. With a dirty fuel filter, the engine won’t be getting enough fuel which means that the vehicle won’t be giving the acceleration performance that it should.
