Not only did I missed those little EGR ports, I missed them even AFTER @Mendel Leisk pointed it out...I had to be shown (in a video) that the damn...
Well...after doing the intake cleaning (again, better), and boring out those tiny ports...I took it on about a 10mile testdrive, up to 60mph...not...
This stuff (or something similar)? [MEDIA]
Thanks for the suggestion of using a pistol-bore brush. Nope. "We don't clean parts, we just replace 'em" is essentially what they said. And...
Searching through old threads, I found this one that described my symptoms EXACTLY....
First let me apologize for necro'ing an old thread, but it's relevant. The bit about it NOT happening when it's cold really puzzled my grizzled...
After getting a message from the Prius tech about those passages being blocked, I took a closer look at picture (close-up) of those tiny holes you...
Didn't end up being the injector either. No change with brand-new injector installed. It's at an official Toyota service center now, maybe they...
The other 3 are giving a big fat zero on misfires, tho. And at a bit over $100/each, that's a bit much. Wouldn't wiring problems result in a...
Is words were "swapping an injector is such a pain, we might as well just replace it. I agreed with the sentiment.
The misfire & "shake" (we confirmed by watching the misfires on Cyl4 count up by a dozen or more PER SECOND at a time on a test-run) were getting...
Which I'm told is un-stoppable once it's started. All you can do is mitigate or slow it.
If you've got it apart that far, you might as well get it off & get it cleaned. You've done 90% of the work to get it apart at this point. I...

Actually took it to the shop last week and they (told me they) did the swap-components-around trick (at least the plug & the coil)...and the...
Figured it out & got some screenshots. The stupid tool that tells me a single line of fuel-status info takes up half the damn screen real-estate...
Sorry, couldn't resist a "that's what she (he) said joke". And if it was an orifice on that intake, it got blasted. Most of the gunk came out of...
Yep, made sure every orifice of that thing got attention. ...and dammit, "that's what he said"
Can't answer to the EGR Valve itself, that was cleaned by the mechanic. The cooler was 100% clogged, took a half hour & about $10 worth of...
Can anyone with more experience with TorquePro weigh in with which PID Leadfood is talking about? I've been all the way through the list & don't...
