Replaced throttle positioning sensor, Advanced says its the 4 o2 sensors. now when i get up to 25 and it tries to go to secong the rpms keep going but i go no faster, have to lift until it shifts, cant floor it at all no matter if im sitting still or trying to pass someone, is this the trainy. got trainy filter and fluid to replace today Hammer Time Ultimate Carjunky / Moderator May 21, 2011, 4:16 AM Post #2 of 5 (2622 views) Re: 2000 chevy blazer 4x4 Sign In It does not need 4 0/2 sensors. That's another example part time parts clerks trying to be technicians. Post the exact code numbers that were stored. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. rosco New User May 21, 2011, 4:29 AM Post #3 of 5 (2614 views) Re: 2000 chevy blazer 4x4 Sign In once they said 02 sensor i stopped listening. its more serious then a sensor. b4 that they even said the lid on the gas tank. they r no help. replaced throttle positioning sensor because of them, no help there. my thinking is going towards the junkyard Hammer Time Ultimate Carjunky / Moderator May 21, 2011, 4:31 AM Post #4 of 5 (2611 views) Re: 2000 chevy blazer 4x4 Sign In Take your thinking back to the code numbers and post them here. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Quote ">>rpms keep going but i go no faster<<" unless I read that wrong that's slipping! Not good and changing trans fluid and filt now will probably show a lot of muck in pan from plain wear from slipping which it won't do much longer - get into a road service/tow club now, T   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
