My engine slowed down with very little power. I have a 2003 GMC Yukon with about 258,000 miles. I was able to get home doing about 35 mph. My info display read "reduce speed engine". My engine light was on. Engine was running very very rough. On star ran a diagnosis and said it was a Throttle Control System Problem. Any hints or suggestions of what is wrong?

I had same symptoms on my old 2003 Tahoe and it was the throttle position sensor. You cant replace just the TPS, you have to replace the whole throttle body. It's all one peice. It's not that expensive. I think I posted about it previously, so you may be able to find my old posts.

I have an 03 Yukon with 150k on it. Have had the "reduced engine power" off and on for last few years. A couple of months ago I installed the new throttle body plug as per GM tsb info. Did not correct the problem. A few weeks ago i installed a new throttle body / throttle position sensor assembly on ebay and have not had the problem since. GM part number is 12570800 and AC Delco part number is 217-2293. I got mine for $ 200.

I also have a 03 Yukon and went through all the possible problems mentioned in the tsb. New throttle body finally fixed it. My 2011 2500HD just had exact same problem. Turns out GM is still having problems after 10 years. Evidently with my 2011, they now make a kit for replacing only the throttle position sensor

      WTI futures / speculation is just that. WTI futures <> current 4-7% inflation and national average gas price over $4.00/gallon.   The spot price, at delivery, is currently $87-$95/barrel which is why gas prices remain high.   Edit: oH mY gOd mEnTaL BrEaKdoWn In tHE pOsT aBOve mInE.

      He does, actually. In another unrelated video he mentions the president called him in the middle of the night to relay some information on a cause (religious based) that he's invested in. Glenn expressed concern that another leftist administration could wield too much power with some procedure the Pentagon was using, classifying certain religions a certain way. Being that he is LDS (Latter Day Saints), he gets hate all the time from ALL over the political spectrum, so he's invested in this. Trump called him back at 5AM to tell him he had made some changes to that classification.   So, yes, they are and have been in contact regularly since the start of the administration. Glenn, of course, always asks his permission before discussing anything on the air.   I already spent an hour or more just searching for these videos. I may have my numbers wrong - I'm not a numbers guy. It may have been a MILLION barrels, not 1.5. The point is, our President, by his actions, gives a crap about America, and US - this is completely OPPOSITE the actions of the prior administration who projected hatred for anyone who wasn't following the left's edicts in lock-step.   Remember, they called January 6th an "Insurrection", when there were ZERO weapons among the crowd, undercover FBI agents agitating the crowd, along with paid leftists acting as aggressors, egging the crowd on in an attempt to whip everyone into a frenzy. It's all been proven.  Pelosi refused Trumps request for more National Guard troops. This smells 100% like an inside job for those with critical thinking skills. Only a handful of guys in the crowd got wrapped up in that, thankfully, but EVERYONE was searched out based on cell phone data, and charges were brought against many. And 6 or so people were locked up and left in solitary confinement for YEARS with ZERO due process!! If you give the slightest crap about our Nation, REGARDLESS of your political leanings, this should frighten you to your core. This is what men suffered, bled, fought, and died against 250 years ago!   This has gone FAR BEYOND left vs. right. This is a  threat to America, and our way of life. This is PRECISELY why Trump, a BILLIONAIRE who could have chosen to take Melania and sit on some tropical island that he could afford to buy himself and RELAX, instead chose to run for office, get hate from literally every corner of the media, get ATTEMPTS on his LIFE constantly, and begin to repair some of the severe damage that's been done to this Great Nation.   I don't know why I bother wasting my precious time here. Everyone has their minds made up. They won't realize we all were correct until it's too late ... after they elect another tyrant that hates America to office (Obama), or another puppet whose administration is secretly running the show behind the scenes (Biden).

      By Newduramaxh*ar · Posted

      Hello, Im in a bit of a bind maybe someone could help me out.  We towed our trailer, up a pretty steep incline (395 north of Bishop) done it before no issues. I got to our campground turn truck off, i restarted the truck about an hour later  and check engine light turns on. Found DTC P2C48,  unable to reset.  This morning i removed the plug, there's 12.12v at the plug. Reservoir near firewall is full of coolant, checked for leaks nothing. I dont hear or feel the pump turning on. My dilemma, is nearest dealer  is 4hrs away that has the pump instock. Is it safe to drive? By me checking the available voltage at the connector and not hearing/feeling pump turn on, is it a bad pump? Please help...

      The figure bandied about is "100 million barrels" so I think a decimal is off somewhere. But that doesn't change the outcome much when the expected flow through the Strait through over the same time should have been more than 2,000,000,000.   So 5%, if that number is even true, and there's sufficient data to believe it's not. Give that man another Fifa peace prize! 5% is less than the flow of a grapefruit-sized prostate blocking the release of cheap lager after a night of bingo.
