I have a 2009 GMC canyon that has no throttle response
Is the check engine light on, or yellow wrench light symbol? Hook up a professional grade scan tool an check for DTC'S - diagnostic trouble codes . No throttle response , problem with electric throttle control . Two position sensors in gas pedal assembly - two position sensors in the electronic throttle body - plus a DC motor to control throttle plate position. Other poster has no clue. Dirty throttle body would not cause no throttle response, rough or unstable idle for sure.
If this answer helps you, please donate whatever you can. Thank you!

2005 GMC Envoy XL 4WD is stuck in neutral. How do l get it unstuck?
Q1: REVERSE IS DEAD TOO?>
no VIN told or if transmission is automatic. or manual
no engine told of 3 and tranny size matches engine power
4L60-e transmission is on 5.0L gm engine.
I think most Envoy are A/T boxes. USA, shows this .
PRNDL. Reverse. Drive and Low fail? say those words
is east,.
the transmission needs service, vast problems possible
they are complex.
causes, top:(SCAN THE PCM IS WISE SEE IF IT SEES A HUGE PROBLEM THERE.) BUT REVERSE DEAD IS A VERY BAD SIGN. SCAN THE PCM FOR SOLENOID ERRORS!
- ATF oil leaked out of box and now dry, diP stick it? ATF smells burnt or looks like TAG is bad news. or metal flakes in the ATF DRIPPED TO A SHEET OF PAPER.
- fuses blown but most time reverse still works.!!!
- transmission shift linkage failed. (the service manual covers the steps to check that, Read the SM?)
- transmission shift solenoids bad. (reverse? has none)
- transmission is bad. (means removal time)
NOW IF REVERSE FAILS
ALL THESE THINGS HAPPEN TO ATTAIN IT.
you asked so here is a complex answer, (not all)
AND LOTS MORE TO FAIL.

2009 GMC Acadia rpm is running high and giving p0497 code
hot or cold engine High and how high is RPM not told.
no it is not evap failing to cause RPM failures.
2 problems sure, but not THE problem
well gas cap loose or bad is first. simple fix that is
costs nothing, and cap good or cap bad $10 fix.but not RPM off.
then purge solenoid.
RPM high is the best clue here. for sure
mine fails every 50k miles it seems and pull the valve
and flex the valve inside while spraying silicon oil spray inside it
and it goes 50k more miles costing me 50 cents lube.

Evaporative Emission (EVAP) System No Flow During Purge
the test in the service manual are extensive
example
- A loose, missing, or damaged fuel fill cap can cause this DTC to set.
- A stuck closed, blocked, or restricted EVAP canister purge solenoid valve, can cause this DTC to set.
- A blockage or restriction in the EVAP canister purge solenoid valve vacuum supply hose, EVAP canister purge solenoid valve purge pipe, EVAP canister, or vapor pipe, can cause this DTC to set.
- A temporary blockage in the EVAP canister purge solenoid valve, purge pipe or EVAP canister could cause an intermittent condition. Inspect and repair any restriction in the EVAP system.
- To help locate intermittent leaks, use the J 41413-200 Evaporative Emissions System Tester (EEST) to introduce smoke into the EVAP system. Move all EVAP components while observing smoke with the J 41413-SPT High Intensity White Light. Introducing smoke in 15 second intervals will allow less pressure into the EVAP system. When the system is less pressurized, the smoke will sometimes escape in a more condensed manner.
- To improve the visibility of the smoke exiting the EVAP system, observe the suspected leak area from different angles with the J 41413-SPT .
- Observe the Freeze Frame/Failure Records vehicle mileage since the diagnostic test last failed may help determine how often the condition occurs that caused the DTC to set. This may assist in diagnosing the condition.
the valve is here "P"
#10 if it leaks running, stuck open rpm can go wild
or the hose to it is cracked
2002 GMC Sierra 1500. I only have high speed wipers and they don't park when I turn off.
anon
turn off the key (wrong)
or turn off the wiper switch (good0
or both, not told.'
here it is,
as you can see , it all loses power key off, as in ALL DEAD.
BUT IF YOU TURN just THE WIPER TO OFF. AT ITS SWITCH
IT MUST TURN OFF. AND AUTO PARK (switch not bad)
THAT MAGIC HAPPENS BY THE YELLOW WIRE BELOW RIGHT SIDE.
so yellow wire busted.(mice eat it, IDK)
or wiper guts bad( the internal so called PULSE board)
marked control logic below.
