Electronics reconsidered
I am new here, but have owned a 87 4wd 4runnner, 4wd montero(terrible), 4wd 95 pathfinder( good experience,still own, thought about selling.. may not now), and my current suv.. 06' 4runner sports edition 4wd. I have believed the 4runner to be a great SUV for my lifestyle (but it only has 59k) and one that I would own till at least 200k. The vehicle has been great as far as reliability, granted I do baby it and have yet to really test it offroad that much. It is too new and nice for me, mainly serving as my daily commuter.
I reconsidered this Friday night. Upon starting the truck idled erractically, similar to moisture in the distributor & rotor. I noticed this and cautiously put the car in reverse. The tranny by wire shift is a bit delayed normally and as the tranny engaged the rpms surged...jolting me back upon shich I placed the tranny in neutral and immediately the engine revved to 5500rpms. I turned the truck off and put the tranny in park. Upon restarting the rpms surged to 5500 within a second and I cut the truck off. I restarted then everything was normal. I was lucky I did not take my hand off the shifter and was very cautious during the truck's intial abnormal behavior. Of course to put the truck in reverse one must have their foot on the brake. I never touched the accelerator at all during this scenario. When I restarted it I did not even have my foot on the brake. I did research on this "surge" or "runaway phenomenon" for last few days and have found disturbing facts and news about toyotas, especially since they have adopted strictly "wire technology" without any reliance on mechanical or secondary "wire" backup mechanisms. As much as everbody has derided claims of people experiencing this I know myself this is a fact and have overcome naivete with the realization that I am not in control of the car....the ECU is. This is cars' computer that interprets the drivers mechanical actions and transfers that directly to the electronic throttle. There is no separate secondary override that is mechanical or even computerized to intercept b/tw the two. An aberration in the ecu was sent to the electronic throttle or confusion b/tw them resulted in this event, w/out my input. In other words...the computer and the throttle decided the ultimate outcome, w/out my doing. Anybody else experience this?
I'll stop there. Please do not respond as the dealership has, saying "you made a pedal mistake or your Weathertec floormats must have got in the way." That is gibberish.I have been driving for 16 years on and offroad and have had ratty floormats sticking on the accelerator or cups intefere with the pedals...please nothing mechanical could have put the rpms up to 5500 in a second.
