zero limit Posted January 27, 2011 Posted January 27, 2011 This morning dropping off the wife to work Igot on the gas really hard around a corner, and lost all power to my truck. 2004 COLORADO4X4 got message on dashboard stating reduced power and could not get the truck past 30mpgs all the way back home. ANY HELP, It's a 3.7 5cyl. w/42.000 miles on it. I'm having a bad week with vehicles. Thank's, Dennis Quote
jeremyt Posted January 27, 2011 Posted January 27, 2011 I am by no means an expert, but I would take it to an auto zone type store and ask them to run a OBD ( On Board Diagnostic) on it to see what codes pop up. I think most of them are doing this for free now. Quote
zero limit Posted January 27, 2011 Author Posted January 27, 2011 Ya that's my next step, Right now i disconceted the battery cables hoping the computer will re boot Quote
Milton Waddams Posted January 27, 2011 Posted January 27, 2011 Could be a multitude of things best thing is to have dtc's checked. Quote
zero limit Posted January 27, 2011 Author Posted January 27, 2011 Had battery cable un hooked for an hour then rehooked them up now every things seams to be back to normal. Thank's for all the input guy's Dennis Quote
Nice_Bass Posted January 27, 2011 Posted January 27, 2011 well...i would have guessed an o2 sensor....but i am not a car guy by trade by any stretch. Glad to hear it is corrected. Quote
Stasher1 Posted January 27, 2011 Posted January 27, 2011 Is it possible that you hit the rev-limiter when you "got on the gas really hard"? Maybe the truck's computer put it into "limp mode" to keep you from tearing something up? Quote
FordNFishinLover Posted January 27, 2011 Posted January 27, 2011 I know your problem, its because its a "CHEVY"! Too me it sounds as if its a computer problem. Running the codes would be the first step id say. Quote
Super User bilgerat Posted January 27, 2011 Super User Posted January 27, 2011 Is it possible that you hit the rev-limiter when you "got on the gas really hard"? Maybe the truck's computer put it into "limp mode" to keep you from tearing something up? This is likely what happened. Something (oil pressure, water temp, any number of things) ran outside of it's parameters and it went into self protection. Pulling codes is the right thing to do, but Auto Zone is the last place I'd have diagnosing my vehicle. Speaking from experience, codes can be triggered by other things not related to the item that's supposed to be at fault. Often sensors share a common ground (return) path This is best diagnosed by a qualified tech. Quote
CanalStalkin Posted January 27, 2011 Posted January 27, 2011 Sounds like a limp mode to me also. If you bounced if off the chip it will more than likely do that. Quote

Both of my newer cars will do the same thing to protect the engine and transmission. Quote
HossFly Posted January 28, 2011 Posted January 28, 2011 I was once told that OB2 and OB3 engine controls have a memory of the vehicle driving "history" and this type of thing can happen if you do this; sorta' puts it in safe mode? Also told that if you remove the negative post for longer than 45 minutes, it will re-set the computer..... thus said, maybe you need to nail it AFTER you reconnect..... who knows, it could work?

HossFly Posted January 28, 2011 Posted January 28, 2011 Uh, that would be OBD2 AND OBD3......dang Bud Light Quote

Take the positive post off, hold it to a ground (any good ground will do) for 1 min. This will reset the computer. It will take about 50 restarts to reset values on the computer. It will also clear any codes. Quote
Super User SoFlaBassAddict Posted January 28, 2011 Super User Posted January 28, 2011 Works the same way in both my Magnum and my Charger. Pulling fuse 11 also does the same thing. I forgot the exact terminology for it though. On the newer Dodge vehicles, you can also tell what codes are popping up by doing a key cycle a few times. Can't remember the sequence off the top of my head. I believe it's off turn to acc, then repeat twice more ending in acc mode. The codes will pop up on the dash panel. Quote
Super User Redlinerobert Posted January 28, 2011 Super User Posted January 28, 2011 It's the flux capacitor. Definitely. Quote
Super User SoFlaBassAddict Posted January 28, 2011 Super User Posted January 28, 2011 Darn that plutonium for being so hard to find. 1.21 gigawatts?!!?!! Quote
