      Thank you for your support making this video. I just fixed my 2009 Chevy Silvarado 150 with this video. Went all the way with your fix but disconnected the battery so the computer would be forced to learn all codes again and adjust the throttle body itself. Problem solved for me. Thank you so very much!!!

      I have a 2010 Chevy equinox with the 2.4 ecotec doing the samething. Its threw a p228d code. But the code goes off and on. I went ahead and replaced the throttle body and both rail pressure sensor's. But im still having the same problem. Jumping and stalling at stops and bad idle. Could this be the pedal sensor ?

      I'm having the exact same symptoms on my 2011 malibu. but the code said the map sensor. I replaced it. it's still doing the same thing. it's still saying map after I erased codes. I traced the wires all the way to the ecm. all good. I cleaned the throttle body and maf, i replaced the intake becuase i read the the plastic one for the Malibu is notorious for leaks. still the same thing. only thing I can think of is the ECM. I took the throttle body apart and checked everything just to check. no play in the gears......I havent checked the pedal yet. it's hot outside tho. so maybe tomorrow

      I was told that also the air pump will come into effect, since it brings clean air for combustion, I might replace the air pump since it has a lot of miles already

      I changed mine for a brand new one, whole body, it worked but after a while the reduced engine message came back on. I don't know what else could it be?

      My 2015 Buick Verano just started doing this. It will come and go and hate when it does it on the freeway. Hope I can get it fixed.

      Was the car shaking as well? Mine has the same error without reduced power and is shaking. Think it’s the same thing?

      We have had this happen about a dozen times on our 2004 Escalade.  For some reason it tends to happen if we drive off road.  Not four wheeling or anything, just like on a dirt road or gravel.  The fix so far has been to turn the engine off, wait about 10 seconds and restart.

      I replaced my throttle body on 14 acadia. Helped for a month. Then started doing again. Took to dealer. Replaced alternator helped for six months then came back. Back at dealer. Hate GM electrical system. I thought throttle body was my answer but keeps returning

      I have a 2009 Chevy HHR. I was getting the reduced power message and the car was running horribly. I replaced the Throttle Body with the sensor. I still got the message and it ran bad. I replaced the gas pedal and sensor. I now get the message but it seems to run smooth. I've got the battery cable off right now trying to reset everything but I think I still have problems. Any suggestions?

      thank you for your contribuition for all the people that have the same issue but to be honest each case is different is no t always the same, let me tell you my experience, l had issue with my differential and i spend a lot of money with 3 difents mechanic that just want to steal my money because one said that was the cv joint other that diffential but, at this time i dont know exactly what was the problem, the point here is that finaly i fixed the diferential problem but the engine power is reduce light sudenly came out and the mechanic thief said that was the throle body, but finaly i found a honest mechanic and was something about the gas sensor, to end this tip to my experience not always is the throttle body think more the two time to move at your throttle body because is really delicated
