****CHECK OUT THE VIDEO ON HOW TO FIX THIS!****nwww.youtube.com/watch?v=8fQ01Wn3YPgnnnThis is my mom's Chevy Suburban that recently started having running problems.
The engine gets reduced engine power, and runs ragged.
It happens while driving, and it has happened 4 times now.
If you have any ideas about this, please tell me.nMore videos later.nnUpdate.
Shortly after filming this, I found a GM service bulletin on this problem.
It said the problem had to do with the throttle position sensor being out of sync with the CPU.nWe took it into the dealer, and I wrote the specific bulletin number on a piece of paper and sent it in with the car.
It was fixed under warranty, and the Chevy hasn't acted up since.nHere is the service bulletin;nBulletin No.: 11-06-04-007BnnDate: April 16, 2012nnSubject: Diagnosis and Repair - Malfunction Indicator Lamp (MIL) Illuminated, Reduced Engine Power Message Displayed, DTC P2135 SetnnModels: n2008-2011 Cadillac Escalade, Escalade ESV, Escalade EXT n2009-2011 Cadillac Escalade Two-Mode Hybrid n2008-2009 Chevrolet TrailBlazer n2008-2011 Chevrolet Avalanche, Colorado, Express, Silverado, Suburban, Tahoe n2008-2011 Chevrolet Tahoe Two-Mode Hybrid n2009-2011 Chevrolet Silverado Two-Mode Hybrid n2008-2009 GMC Envoyn2008-2011 GMC Canyon, Savana, Sierra, Sierra Denali, Yukon, Yukon Denali, Yukon XL, Yukon XL Denali n2008-2011 GMC Yukon Two-Mode Hybrid n2009-2011 GMC Sierra Two-Mode Hybrid n2008-2009 HUMMER H2 n2008-2010 HUMMER H3nEquipped with Engine RPO LFA, LY2, L20, LMG, LC9, LH6, LMF, LH8, LH9, L76, LS2, LY5, LY6, L92, L96, LZ1, L94 or L9HnnAttention: nIf a vehicle is encountered with this condition, DO NOT replace the throttle body.
