SOURCE: SES light then Reduced engine power light, loss of engine power

Hi It me Mohammad Siddiq my dear. First of all it will be wise of use to take your vehicle to a dealership or any other fully equipped w/shop. They can better tell you what the fault your vehicle has. But at the same time if your friend has the same model vehicle so you can exchange some parts with that vegicle, e.g., Mass Air Flow or TPS (Throttle Position Sensor) and can check your vehicle. These parts do not need to be programmed with scan tool. Just Simply replace these parts and switch on the ignition and wait for 01 minute, then switch off for 30 seconds and then start the engine. Now road test your vehicle, if no SES light or reduced power then there was fault with the part/s replaced. So Return those parts and now you must replace these parts with new or used ones. Anything else I may be contacted on my yahoo id siddiq_pathan@yahoo.com. Thanks. I am an auto technician and working in a GM dealership in Saudi Arabia. I am from Pakistan.

SOURCE: The reduced engine power light came on my 2003 GMC

If you live near an Autozone, they can diagnose your code for free. This is gm's attempt to protect the engine from worse damage by limiting the power output of the motor...
it could be major, could be as minor as a gas pedal sensor...
get the code..

SOURCE: Service Stabilitrak-Reduced Engine Power

the engine light is a generic fault indicator in your car to point out something is not quite right with the engine, having a loss of power as well is also known in some areas as Limp Mode or Safety Mode. it means the car is restricting the power it gives to ensure no damage it done to the engine.

the only certain way to find out what is wrong is to take it to a garage that has diagnostics equipment that can read the fault codes from the vechicles ECU (the fault codes will be the reason the light on the dash has come on as its reporting a fault somewhere)..

your mechanic should be able to tell you what is wrong with the engine from that and give you a more accurate cost at fixing it.

Was there a bulletin issued to extend a warranty for spark plug wires, maybe #10250


Yes....10 years or 120,000 miles
Condition
Some customers of 2007-2009 model year Chevrolet Equinox and Pontiac Torrent vehicles equipped with a 3.4L engine (LNJ), and 2008 Chevrolet Express, Silverado; GMC Savana, Sierra vehicles equipped with a 4.3L engine (LU3) may comment about rough engine operation and the illumination of the Check Engine Light. This may be caused by spark plug wire boots that do not provide a sufficiently robust dielectric seal to withstand the high voltage required to fire the spark plugs.
Special Coverage Adjustment
This special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. Dealers are to replace all spark plug wires and, if necessary, the spark plug. The repairs will be made at no charge to the customer. For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after January 5, 2011, are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to January 5, 2011, must be submitted to the Service Contract provider.
Vehicles Involved
Involved are 2007-2009 model year Chevrolet Equinox and Pontiac Torrent vehicles equipped with a 3.4L engine (LNJ), and 2008 Chevrolet Express, Silverado; GMC Savana, Sierra vehicles equipped with a 4.3L engine (LU3).

2003 gmc savana rough idle then shuts off


Does it have any power when you start moving? I've seen a lot of plugged catalytic converters. You may want to have an exhaust back-pressure test done.

GMC 2500 Diesel, reduced engine power??


Just my 2 bits, go through a spring cleaning checklist. Plugs could be fouled up, fuel could be contaminated, you already did the filters. Do you have it chipped or programed? Change the exhaust lately? Do you have the code number? Autozone will scan it for you for free, tell you the code number. Again, just my 2 bits.

What does reduced engine power light mean and have no acceleration. Turned truck off and reduced engine power went out and everything is ok again; however afraid to drive the truck anywhere now. 2004 GMC...


this model has what they call fly by wire.. no accelerator cable. If the computer detects a problem in the thottle system it will not allow the engine to accelerate and will show reduced power and possibly set a check engine light. The dealer usually wants to replace the throttle assembly which is very expensive and usually un nessesary.
I have had a lot of succes with just cleaning the throttle plates real good.
