The same way that forcing too much EGR via the Techstream active test for the EGR valve causes misfires in all the cylinders, only here they are...
That very much sounds like the EGR passages in the intake manifold need cleaning. They are proven to clog unevenly, which leads to misfires...
How you liking the lift kit?
Forgive me for thinking the bigger picture is to make use of the (so far rare and mostly missed) opportunity to have willing participants gather...
If we're making the ideal wishlist, I'd also suggest photos of the intake manifold EGR port cloggage. (Do we have a correct term for those small...
That's a puzzle. I assume that without pressing the brake you're not getting into accessory mode either? If you haven't done so, search these...
Sounds like you walked through hell on that one! Glad you shared it here, maybe we can find an easy enough way to save the next poor soul a few...
Interesting. I thought maybe they were trying to pull the sensor wire further out of the path of the inevitable puddle in the throttle body. I'm...
I noticed on our 2012 that the MAP sensor looked different from the 2010. I was afraid I had broken off the sensor wire on the 2012. But I think...
Heh. I do enjoy the seminar when it fits in browser page or two. Kinda wondering if the hybrid application (not so much the Atkinson cycle but...
Yikes. At least you can safely rule out thermal fatigue on that second one! In the "good old days", the rule was if you blew a HG you were...
Yeah, I mean the headgasket / EGR connection arose because gen3s are seeing early HG failures and we don't really know why. Gen2 taxis all...
Full marks on point 1. (After the gen3 more than killed all regulatory requirements on NOx, Toyota still doubled down on EGR in gen4 for the...
There's also the notion that partial clogging of the cooler leads to the EGR flow not being actually being cooled. See the reference info in this...
Well I can see you won't be taking my word for anything (:)), so check out the "eco" version of the gen4 in which Toyota specifically put the...
That's why I do let mine warm up but only just enough for the ICE to turn off. Charging the traction battery to full at idle like OP is actually...
Have we lost sight of earth? The quick EGR unplug test isn't going to hurt your engine in the real world, and in the vast majority of cases if it...
When I replaced my 12V battery I connected another battery first using jumper cables to the jumper connection under the hood at the fuse box. (So...
I first noticed that idea in a video by @Ragingfit. He was dealing with EGR on these forums like 5 years ago, and we're still learning...
Definitely confirms that uneven blockage of those EGR ports on the intake manifold can lead to misfire codes (if there was any doubt). And good...
