"Sharp/Biting" Misfires under load are usually Secondary Ignition related......
*At night or in a dark area......Mist the plug wires & ignition coils with some water from a spray bottle & watch/hear for arching.
*Water &/or Oil in the Plug wells.
*Pull all the plugs & check for cracked Isolators(Ceramic).
will keep that in mind, thank you. Didn't do anything today, so maybe it was in my head. It was not a steady miss, just feel like a random miss, like a handful at most on one hill.
Coils, now I have heard complaints about those going, perhaps it's time for me to pick one up for a spare.
Have you logged in to the Toyota Owners site to check any dealer repairs/maintenance done?
Forgot that I had set that up. Go figure, absolutely nothing comes up for that car for records. Nothing.
On the flip side I saw that my truck had the throttle body cleaned at 60k. I cleaned it at 110k or 120k as it had an idle issue. So it sounds like... I'll be cleaning it again soon enough.
Also came across that it had an ECU reflash back in 2014. Which makes me sad as I am getting close to end of warranty on the AIP--but the blockoff / bypass stuff only works if the ECU wasn't reflashed.
