Injector / seal failure or Miss-fire codes.. please post here

[ft_sjo]

I occasionally get popping back in the intake manifold during the cat light cycle. No DTC's though.

[Ryan86]

for interest Toyota South Africa has loaded a software upgrade to our 86, which is to prevent this problem.

you may want to look into this code ZA1JA01G

The upgrade also eliminates the idle drop issue.

hope this means something for you guys.

Which problem? The popping back in the inlet manifold or leaky injectors?

[RevoG]

Mine had that same pop yesterday. First time ever but definitely the same pop. And it happened just once...

this frightens me, I keep getting P300 and P302 codes.

P0300 is random multiple cylinder missfire, P0302 is cylinder #2. I'm guessing yours may be the cranks sensor shim issue issue since you are getting P0300.

What's the heading of the thread wiseass.......


The SW upgrade prevents the injector issue with the seals, evens out the spray evidently.
Look it up....

Umm, so far there are several issue being discussed in this thread so a little clarification won't hurt....

Do you have more info on that update? I searched the code but didn't really come up with much. Is that an update for cars globally or just south africa?

21k miles on the car, Perrin CAI is only modification under the hood atm.

This being the 2nd time back to the dealer ship for another DI leaking. [ame="http://www.youtube.com/watch?feature=player_embedded&v=VnFa2IvNs9g"]Frs popping noise when given throttle free revving or cruising, rolling on throttle to pass. - YouTube[/ame] is what mine does in only low-mid rpms 50%> throttle or in N.

Only had 1 CEL, p0351 back a month ago Right before I got the firecracker noise from the bay. This past week I got the noise again with no CEL. Dealer said it was my other DI.

So now they're replacing all of them, with yes completely new DI Injectors straight from Japan, not from the warehouse where the first one was shipped from. I was told today by the GM ( a good friend of mine) in person that I am going to be the first one with these new DI's that should be a "permanent" fix.

I'll post more info when I know more from said above.

Is there a superseded P/N?

^ This..

Also, it may help if people who have had seal failure post the build date of their car...

I've pinged epifan to see if he has a copy of the updated rom mentioned above yet. If he does I should be able to compare maps and see what they changed, assuming the changes are in a defined table.

I know on cold start the ignition timing goes to -15 degrees and assume injection timing is retarded as well to intentionally get a portion of the combustion happening in the exhaust to light the cat off....

I wounder if this is some how melting the seals... or if it is simply an installation issue... the manual is very clear about not scratching or damaging the seal during install. Guess it could also be a design issue... a new part number would certainly suggest the latter

Will have one soon. Rep couldn't give me much details, he just knows it was shipped and on the way to my dealership. I'll know more once it arrives and watch the mechanic do the install.

I'll check the build date as well.

I got mine June 1st, watching them take it off the truck. It had a "#1" in the top left corner of the windshield, which meant it was the 1st one shipped in my dealers SE region.

Sometimes it doesn't pay to be first :-/
