Your Silverado's ECM has detected an issue and has reduced the engine power. You going to have the the truck scanned for the DTC codes so you can address the issue that is causing the reduce power to activate. Auto Zone scan free of charge, good luck and keep me posted.

You may be correct with what you think the problem may be, but another good thing to check is your coolant level. A low coolant level could cause false readings from you coolant temp sensor, which in turn will cause an engine hunting condition that you described.

What causes the esc light


The ESC Off light comes on and pushing the ON/OFF switch does not put it out. If I shut the car off and re start, the dash light goes out sometimes; May return the next time I start the car..I've heard that the problem has something to do with the brake sensors. People usually notice that the brake lights go crazy as well.My 2009 is in the shop right now for my check engine light. My ESC light is also coming on as well. They ran the diagnostic and the only code that showed up was a faulty crankshaft sensor. I'm wondering if that is affecting the ESC. I know when the ESC comes on I get hesitation before it. That might be the crankshaft sensors doing. They said no other codes came up.This problem was recalled back in 2007-2008 and is presently being recalled on some vehicles. This appears to be a common problem with Hyundais who refuse to address the problem unless the cars are recalled. Please write the National Car Safety so that they can request a recall. Without these complaints, the recall will not occur and everyone will be paying out of pocket for a manufacturing defect.

Many o2 sensors have gone bad but 50% of the time when a code is set on a car about an o2 sensor there is another cause which is changing the emissions & setting the o2 code (ex. vacuum leak, bad plug, injector, it could very well be the cat etc.) The root cause of the problem must be found NOT JUST READING CODES! TAKE YOUR CAR ELSWHERE.

Citroen c crosser anti pollution light


Anti pollution light, I never heard of a Check engine light being called that.
Read on please.

Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
