Separate names with a comma.
Obi-Wan took a look, says it's the transmission damper that's making the most horrible noise from the transaxle area (I agree). In his opinion,...
That's not horrible... but it's not correct. Sticky pins, sticky e-brake mechanism, sticky cable, more rarely (but easier to miss in routine pad...
The article was fine. The author's logic is fine. The title is silly. He isn't saving a failing head gasket, he isn't trying to save a failing...
The Prius is supposed to have a very low drag friction brake system. Your shop butched it up (there are a couple of ways that can happen on rear...
Dumb a&& title (probably the work of a dumb a&& editor).
Dropped car off with local Obi-Wan. On way over, ears and butt dyno say it's misfiring at low/mid power, but still fine at idle and high power.
In Techstream, there is a Knock Correction Learn Value, that in my case is 21 degrees. Is this typical? That's a mighty big number.... (edit)...
Thinking about this for a minute, I'd bet a lot of money (about the cost of a head gasket job, for instance) that what I'm seeing isn't LSPI....
If what's going on here is LSPI... holy sh1t. Is there any evidence that this is a thing in 3rd gen Prii?
This car has been on synthetic since new. In it now is 5w-30 Pennzoil Platinum, last changed about 1500 miles ago. Previous oil changes I've...
Thanks.... that was a great reply. So you are still going with "misfire". Alright. What is a/the misfire scenario might I be looking for?...
I understand the mechanical design of the transmission. I agree that the "chugging" is roughly speaking engine rotation frequency. I get that...
Checking coolant for exhaust is a good idea. I have not done this, but there is absolutely no sign of white smoke coolant loss coolant in oil oil...
Drove the car over to an independent mechanic this morning, about 15 - 20 miles on rural back roads. It's pretty easy to drive "around" the death...
Under charging load in park, engine rpm is about 1100. MAF is about 7 g/s, Manifold pressure 10 psi (absolute).
The situation, this morning. Car is in Park, Defroster is operating. Engine has switched on to charge the HV system. Engine is warm. [MEDIA]
Two misfire related questions.... a) what is the misfire "margin" reported in techstream? b) Can an absence of misfiring noted in techstream...
Yeah, I'm going to take a look at that as well... but I think behavior w.r.t. drive selector makes this one unlikely.
Everyone else is out of ideas too? As far as I can tell, the engine is running properly. The last thing I did yesterday before running out of...
Naw. Plugs are from McGeorge Toyota. All indications are that the ignition system is fine, stem to stern.
