  1. F150 electric

    Can't argue with any of that... I have a weird feeling that gasoline will be around longer than we think... Cheers A factory fresh diesel, today, is actually, very clean compared with as little as 20 years ago. But, an ambitious tuner can wipe that out to be sure. Sent from my LM-G710 using Tapatalk
  2. F150 electric

    I think the inconvenient reality will remain for some time - - - hydrocarbon fuels offer unmatched energy density. Furthermore, the internal combustion engine technology isn't exactly dormant either. Let's be honest, if someone had told you, in the early 70s, that we would be driving 400hp 6.2l V8s in a pickup truck and realizing 20+ mpg cruising at 70 mph on the highway in the near future, we would have thought that person had spent a bit too much time in San Francisco during the lsd days. If, furthermore, this person had said all that, and said that there would be little more than CO2 and water coming out of the tailpipe, you'd have written them off completely. We are there. I believe that the future will bring vast improvements in IC engine technology as well as OTHER mobility technologies. It will be little more than amazing to watch. MY money is on a tremendous advance in hybrid technologies... but still incorporating a (maybe small, pressurized) IC engine somewhere in that package. Just MY feeling. It'll be fun to watch, to be sure. Sent from my LM-G710 using Tapatalk

    Exactly. Battery energy density isn't where it needs to be yet, but may get there at some point. The biggest issue is the US electric grid/infrastructure.. It's on its knees NOW.. Can't imagine what will happen when millions of cars start loading it up as well... I think we are still at least a decade, probably more, away from electric vehicles that provide the utility and flexibility we need, maybe even longer. Also, sooner or later, someone will have to admit that the life cycle environmental impact of electric vehicles exceeds that of gasoline vehicles. That fact has already been documented. Today, electric vehicles are just a very inefficient way to burn coal. Sent from my LM-G710 using Tapatalk
  4. Had a similar, agonizing, issue years ago on my 07 sierra. Mine turned out to be a intermittently failing throttle position sensor. Once that was replaced, problem vanished. Didn't throw codes until tps failed entirely, and had it towed in. They replaced the tps and all was well Just my $0.05 Sent from my LM-G710 using Tapatalk

  6. Squeak in 4 cylinder mode

    Probably the exhaust flapper valve. Search on that. I know I have read numerous posts on that here, and what folks have done to eradicate it. Mine does it too...just doesn't annoy me that much... It actually helps me detect the 8 to 4 cyl switch, as it is otherwise undetectable on these new trucks. Sent from my STV100-1 using Tapatalk
  7. Idiot scratch

    Been there, done that, got the t-shirt. It's an awful feeling. Sorry dude. Sent from my STV100-1 using Tapatalk
  8. Never run that fuel. Generally speaking, alcohol "enhanced" fuels are a false economy unless they are waaaaaay cheaper per gallon. The heating value of the fuel is inversely related to fuel economy. Therfore, lower mileaage. Sent from my STV100-1 using Tapatalk
