drive-train puzzle

I'm not a drive-train geniuse and I don't have an answer for you, but shouldn't these parts and labor cost cover by the warranty?

 

And at minimum, if they weren't covered by the warrenty, why would you pay them if they didn't fix the problem, and infact seem to have created more problems?

From previous cars (not Prii), misfires have generally been caused by cloged or bad spark plugs...

 

Take it to a different dealer. And yeah, why aren't you using the warranty?

 

Not sure what you're problem is but there is no way they should have charged you for them mis-diagnosing the problem. If you still have time I would stop any payment you made then make them agree to a fair price.

Also I'm not aware of a 2005 package 9 when I got mine 6 was the highest.

 

hmm. i agree, if they're just replacing parts and giving it back to you, you shouldn't have to pay for their cluelessness.

so the a/f sensor didn't cut it then? it was a long shot, that one guess out of nowhere having not seen the car. i'll have the husband weigh in whenever i actually see him. might be tonight, not sure.

 

check your fuel pump pressure

it could be contaminated gas. does the car sputter worse when turning to one side at all?

at the very least you should have them refund that second diagnostic fee because the first fix didn't do it. (unless they clearly stated that it may or may not have fixed the problem) since you did get the new a/f ratio sensor you can't really expect them to give that away for free, unfortunately. but charging you for diag again and not being able to conclude anything is a joke. if DH can't give a reasonable conclusion he won't charge the diag fee at all.

Ok, so maybe you should start over, and give us the full information so we aren't just spitting out stuff you already have tried (like the spark plugs). start with the Salvage title (which, BTW, would have been nice to have in the first post so we knew what we were dealing with)... what damage was done to the car and what was done to fix it before you got it? You also never mentioned if this was a relatively new problem (ie it was working before at some point) or if it's been this way since you got it (thus possibly a problem from the salvage?). Also go through, step by step, what the toyota techs tried (such as swaping spark plugs) and the results.

In my game theory class back in college the professor was always giving us demonstrations about how people work to the best of their abilities with the given information, and how you'd always end up with a less than optimal solution if you had less than full information... so give us the full information!

There are some risks of bad parts from such salvaged ones.

Anyway, are you familiar with The Five Stages of Prius Hybrid Operation ?

basically, that couldn't really happen. the fuel control system won't control whether the engine is running (applying spark) or not, it determines whether or not fuel is delivered into the cylinders, and that's about it. regen is not affected by whether or not the engine is running. regen will still work when the engine is running, that's a normal part of system operation.

the electric motor spins up the engine to speed without applying spark, basically acting as a replacement for the starter. the engine is also spinning above about 41 mph (with or without spark) regardless of the situation. fuel is delivered and spark is applied when the engine is needed for acceleration, etc.

could also be injectors, or control software.

when the engine cuts out, fuel delivery is cut and then spark.
