2004 Chevy Tahoe - Reduced engine power message

While driving down the highway, my 2004 Chevy Tahoe displayed a reduce engine power message. The accellerator pedal at that point had no effect on the engine even though it was still running. My manual told me to check the gas cap by lossening it then retightening it. It corrected the problem for about 30 miles, then the solid engine light came back on with the same message. After going through the gas cap procedure again several times, the light and message warning went out. I made it home but am concerned about driving the vehicle for any distance at all now. What may be the problem. There are no service or warning lights that are on.

    I just had the same problem with my 04 Avalanche. Drove it waaaay to a dealer on the other side of town with the limited speed (pain in my ***) but they found the problem. It was the throttle connector. Avy back to normal now.

Got a display message "Reduced Engine Power" the


When you receive this message it means that the computer has put the engine and components into protection mode. This computer has done this to prevent any further damage to the engine or transmission. You have to have the computer of the vehicle scanned to find the problem then you need to get it fixed right away. It could be a number of different causes overheating,Low Oil Pressure,Transmission pump problem, low coolant level, low oil level. Their is really no way of telling from this end without seeing the vehicle.Start by checking all fluid levels, Oil,Coolant,Transmission.If all this is good scan the computer with a OBII scanner or take it to a garage and get it scanned. It may just be something simple or it could be something very serious.Do not drive the vehicle it is worth the cost of a tow truck to prevent further damge if you can not determind the cause and fix it yourself.

Most auto parts stores have Scanners that can read the actual Codes causing the check engine light- usually for FREE. Google the Codes to determine what needs fixed.

the post that everybody refuse to read or acknowledge is the first simple instruction
when ever there is a problem , have the fault codes read first
it is free at autozone and other parts shops
then knowing what the problem is you can have it fixed at an accredited service center for less money that fixing what is not faulty costs
