So I swapped ignition coils #3 and #4. I also checked their spark plugs before that; #3 was wet with gasoline and a little darker than the others,...
I don't think so, I've done it before; you'd want to clamp the wiper motor cable somewhere safe. Also when driving like that make sure to remember...
I had forgotten; I was also thinking of a failing ignition coil. I believe they can randomly start failing like this, but I didn't see how it...
Today out of nowhere our Prius started misfiring, at low RPM. I noticed a shaking when depressing or releasing the pedal (where the rpm is low for...
Update Jan/Feb 2019 for anyone finding this thread via search: I believe this issue was caused by a vacuum leak caused by the EVAP purge valve...
I was just talking about my hoses... There were a few instances prior (several months apart); first time I noticed engine revving high when...
This behavior sounds similar to what I experienced when it's very hot out; I think it's the system avoiding putting load on the battery to avoid...
If a hose popped off the intake manifold, you'd notice the engine operating extremely strangely, you'll have a lack of power, and you'll soon be...

Ok so I got the valve out. It wasn't stuck open but repeatedly testing it with a 12v battery revealed that sometimes it would stick open. When...
Thank you that helps a lot. Ah ok so that plug-in thing is the leak detection pump. [ATTACH] HMM, the inspection process involving the fresh air...
I tore down the under panels and followed the fresh air tube. First it goes to a boxy thing in the corner. (77746-47010) [ATTACH] Then another...
Ok so I believe that is the input of the fresh air line which I reckon is needed to let air in when purging vapors into the engine intake. I did a...
So I got that plastic thing out… and it's just some sort of air filter… between that tube and the outside air. There's no hole in the filler neck...
So about that EVAP leak… I made a crappy smoke machine to pump into the EVAP system and saw smoke coming out from the fuel cap area. It couldn't...
Hey, that looks like the issue! https://attachments.priuschat.com/attachment-files/2015/10/96212_T-SB-0041-15.pdf So their repair procedure is to...
