    2023 Colorado/Canyon 2.7 Turbo EPA fuel mileage ratings released.

    S-10’s are great little trucks. I’ve got a 4.3 2001 2wd, 3.08 gears, 4L60e transmission. Mild engine work and tune. Still gets 28mpg on highway and can cruise easily with the rest of traffic with the taller gears.

    Is it acceptable to use compression fittings/ unions on fuel supply and return hard lines?

    Yep, DI and FI hold enough pressure to warrant a double flare, anything less is pure negligence.

    Is it acceptable to use compression fittings/ unions on fuel supply and return hard lines?

    It might be “ok” on some old lady’s rusted out rear brake lines on her buick (after all, who cares about old ladies?) she’ll probably never press hard enough to rupture the “compression fittings”, and even if it fails, the dual master cylinder will still stop the car. Try that same trick on one...

    Is it acceptable to use compression fittings/ unions on fuel supply and return hard lines?

    Indeed, it is much too difficult to double flare a steel fuel line. …As we always used to say at work, “stupid people keep us in business” :D

    Perhaps you should just thank the man for his service and leave it at that.

    What was the speed limit “around Cincinnati” when you were driving 90 mph?

    I love this car!! 2023 Nissan Z:

    Another heavy GT out of Japan. At least it’s a halfway decent looking car. Unfortunately the last the last true sports car out of the rising sun was the RX7 TT, and that was over 25 years ago 🙁

    Knocking on full throttle from standstill / low speed.

    Incorrect. EGR is not activated at WOT

    Speed limits should be lowered back down to 55 and enforced.

    CEL flashing above 75 mph

    Well, that is an extreme example; however, GM had past issues with binding valves in their Vortec engines that caused similar issues that the OP has. A GM TSB identified the problem, and their “cure” was head removal and a full valve job. While this may have been the “right” way to fix it, the...

    CEL flashing above 75 mph

    Indeed, and sometimes the effect is no misfire under light conditions with no load, but under higher load (like when you’re driving fast, uphill, etc) and more seat pressure is needed, a slightly binding valve or weak spring or combination of the two will be enough to cause a constant misfire. A...

    CEL flashing above 75 mph

    This doesn’t really make sense, and throwing parts at a problem isn’t the way to diagnose and fix. You may consider bringing it to an experienced mechanic so he diagnose and fix the problem. For all you know at this point it could be a lazy valve spring and have nothing to do with ignition.

    I am finding sports more and more difficult to give a hoot about ...

    My “kneelers” reply got deleted because “we don’t talk like that on BITOG” My apologies for offending anyone by saying the first thing that came to mind for those who choose to kneel when our national anthem is played. It was probably brought on by my memories of 9/11, digging for survivors, and...

    25 missions in the most advanced bomber (not including the Horton 229) of WWII. Today we have snowflake actors that “didn’t pull the trigger”.
