rattle like plastic.

I have a rattle going on in my car that sounds like square pieces of mylar clothes pinned to the rear chain stays of a bicycle insert it into the spokes like we did with bicycle cards as kids and it's annoying as hell. And it seems like it's after the engine transmission drive axles out to the wheel somewhere. It essentially happens 28 to 44 mph generally lifting foot off the gas every piece of plastic under the car pretty much is removed The front bumper cover has light damage but does not rattle when wind is applied to that bumper cover and any direction I can put about 200 mi an hour of wind from my blower against the bumper cover at any given place and stand back and do it doesn't make the noise only under the conditions met above it seems like. I've gotten under the car with a 24-in pair of channel locks and move the drive axles and shaken everything in the drive line there's no clicking no reason to believe wheel bearings are bad even though they're at 300K there's no groaning there's just this fart like noise on d acceleration it is not the exhaust We have tried that nothing's leaking exhaust is working great The engine is running great this is not a miss or a death rattle The car runs smooth as butter with the hood up my wife stepping on the gas and watching the engine not a stutter nothing?

 

Good Lord I thought it was posted in the Gen 3 forum That's where I was when I typed it. But yeah this is on the 2013 persona and it just started the other day out of nowhere nothing has changed on the car everything is boringly uneventful engines running great in town especially lift your foot off the gas and you get the sound almost like knocking engine and carrying on but it's not that it's like I can't even imagine something inside the transmission but I just can't see it It sounds like plastic rattling and bouncing up and down very quickly but all that's been removed except for the front bumper cover which I can't make it happen by blowing air with my blower add it behind it under it so I'm having trouble believing it would be that.

 

Apparently it sounds like it's in the transmission like when you when the ice engine is started by the electric motor the electric motor doesn't disengage from the engine and it's just trying to keep up with the idling engine and it's causing this my air cleaner to bounce up and down like crazy make this noise that we're talking about here and there you go so I'll try to post a video in a little while but it's not going to really make any difference I I'm not sure how the electric motor that starts the car uncouples and to find out transmission probably has to come out

 

The link just puts a picture he he oy

 

Hi there it comes this is not my car I just thought the post was interesting just watch it. With my 2013 it's jumping kind of like this but it's not the engine rattling It seems like when the electric motor starts the car it's like the starter is running on a car with a starter It's not disengaging The minute I put it in drive or reverse this noise immediately goes away like the starter disengages and if I don't go anywhere and I put it right back into park the sound will come right back and the air box is bouncing up and down like crazy step on the gas and the engine is smooth as silk and the noise is jumping is gone so I don't know exactly how the electric motor locks up the spleen shaft in order to make the car rotate to start and then it has to let go of that shaft I guess it's electric some kind of electric clutch or something it seems to not let go.

 

So is this one now It's pretty much undrivable and the codes I have are PO108 P106A p3190 p o a o f and c1259 I haven't even looked them up yet but what it sounds like that's causing the stutter it's not at the engine it's right there at the transmission kind of where it meets the motor It sounds like the starter stuck with the engine running I know there's no starter

 

I have absolutely zero chance of rodents this car inside under the hood all wiring looks ridiculously brand new there's not a broken plug or wire in the car yet and it's shocking because usually when a motor change take place there's at least one or two clips that get zapped on the fuel rail or on the coil rail

 

When I look in TIS2 it's giving me some funny throttle body voltage percentages that used to be in the 62% range now they're in the 90 something percent range and something to do with throttle body voltage percentage it says All this different stuff is lit up in mustard color when something's wrong and TIS everything is highlighted in a orangey mustard color It's also telling me that my regenerative braking is not working or there is a problem this problem has progress slowly from the little noise to more noise I am wondering personally if the guy who changed my engine did not torque or tighten the flex plate or flywheel bolts whatever we call this piece the balancer thingy not the plate with the springs in it the heavy steel one that goes on first with the six bolts to the crank I'm thinking maybe he put the flywheel part on one evening and then said all I'm going to leave it like this when I come back from work tomorrow I'll put the transmission to the flex plate and drop it all in the car and he forgot to tighten the six fly wheel flex plate bolts and then he put the spring loaded plate right on to the heavier flywheel looking affair bolted that up then it's out of sight and out of mind as the bolts wore loose the noise started faintly and got progressively louder. Now it sounds like the starter pinion never lets go of the flywheel I know we don't have that in this car so that would seem to mean that whatever in the transmission that locks up so the engine spins and starts and then let's go maybe isn't letting go. There's a little inspection plate in between the transmission and engine like 3-in trapezoidal shape I can knock that off tomorrow and see if I can move the flywheel with a long screwdriver indicating it would be loose and not screwed down because something right there at the back of the transmission before the engine seems to be causing a ruckus like right there where MG1 and 2 are I guess.

 

I still have my original 280K transmission sitting right out here in the shop at removal the engine had the death rattle the transmission seem to be fine I just got a newer one so that the two pieces would be similar when they dropped into the car apparently maybe that wasn't the thing to do totally weird.

 

I'm thinking now it's time to back burner the persona generation 3 in lieu of another generation too and a Corolla or a Yaris on site and then the persona and the 2010 solar roof car can become toys yard ornaments we can play around with and see what we can see but the reality is is my Corollas go 20 years with no problems sure they get 10 mi West per gallon but I don't need that 10 mi per gallon anymore retirement is right over the horizon and I won't be needing to go a hundred miles a day hauling my tools and things. Going back to a Corolla just means I spend more time working hun things that I want to not the vehicle My other 2002 was with my daughter-in-law that was my father the colonel's car it's got $500,000 miles on it and I put an engine in it for $450 the 1NZ had the exceptional oil usage and burning problem kind of like the 2z. But at 500k the Gen 3 would be in probably on its third engine so it's quite a bit more costly and if you don't need the 10 mi to the gallon approximately you just don't need it and eliminates batteries and wiring .
