How is new coil? Is Altezza back on the road.
Finally got to drive it after two weeks, surprised me battery didn't die and fired right up smooth as can be.
Can't wait for summer in it, going be a blast
Welcome... Glad the cold weather did t kill it either ..It did kill mine, but I has trickle charger
It was frozen... As soon as it warmed up it was fine ...
Not sure where you live impul but I think the coldest it got here was 0-1 celsius we are a bunch of sucks on the island .
Let it warm up a good 15 mins before I drove anywhere while I was putting the beauty cover back on.
glad the coil came through for you and your back rocking the Altezza buddy.
Yes megatol really helped me out I owe that guy a beer.
He ordered the part to get it on with his shipment that was leaving I didn't have money until payday he said no worries, got the coil brand new geniune toyota part from somewhere and then xpressed shipped it to me!
Now I want to find new rims for it and should replace the air filter...haha
Mississauga Ontario we had some pipe freezing -20 and colder
Air filter part # 17801-46080
Bumping this up. having coil pack issues in my buddys Altezza we brought over.
Megatol what do you think of these... Crappy knockoffs:
also we need a 12204-88570. PVC valve
actualy im more confused.. we thought there was 2 coils packs not working cause we unplugged the first 2 and while the engine was running and it didnt do anything.. unplugged the last 2 and it almost stalled.
so we switched. put the front 2 in the back. and then tried again.. and it was the same result. the front to being unplugged did nothing..
Did you change spark plugs?
Usually engine ECU should show CEL if something wrong with the coil packs. Just do self-diagnostic and see what the error code is.
Regarding to these Chinese coil packs, I personally don't trust them, always prefer OEM.
Do you have a new Link for doing the Self Diagnostic.. that old one doent seem to work.
but luckily the coil packs are fine.
well teh mystery continues. it ran fine for about a day, then while driving it went down to running on 2 coils again..
same issue again.. could 1 coil be causing all this?
Any check engine light? Often, when coil is starting to die problem is intermittent, I was same on my Gloria: it could be fine for couple weeks, suddenly one coil is down, CEL is on, 5-10 minutes later everything is fine again for another 1-2 weeks.
Best way to check coil is Oscilloscope, even if it is still working but degraded Oscilloscope will show different signal pattern for it. The only problem here, if you don't own one, you have to pay someone with Oscilloscope for diagnostic and it would be probably cost similar to couple new coilpacks.
In my case I just bought 2 new coils, installed them. When problem came back I knew bad coil is still on the engine. I replaced next 2 with previously removed and problem was solved: almost a year now and everything works fine.
Can't you just check the resistance across the coils to see if they are in spec? I know I can do this on BMW's, but I don't know if the Altezza is the same or similar.
Resistance checking is not really reliable way, mostly it will help if coil is completely burnt out. I tested on my failed coilpacks and they were inside the specs.
When issue is intermittent it is mostly bad isolation on the coil tip or coil case due to micro cracks. Due to time, heat, vibration etc micro cracks are developed on the plastic/rubber tips and now coil couldn't hold that 30.000 Volts which it supposed to generate and at less level (let say 10.000 V) it got discharged to the chassis instead of going to the spark plug.
We have 4 and 2 are firing and 2 are not.. However if i switch the 2, so the other 2 are there and the firing 2 are now plugged in.. i have the same thing happen again..
So would one faulty coil cause a random chain like that to happen..
K so the Altezza doesnt have a TE1 contact..
but i found this:
and i got this response.
So you mean 2 specific cylinders are problematic. Assuming you changed spark plugs and coils are fine, the only reason that there is no sparks is absence of ignition signals from ECU. Here oscilloscope will be useful as well because it is possible to record the series of the signals and analyze it in time.
Kind of strange so many electrical issues on this car (as I understand power window issues were on the same car), wondering if it has some flood/water damage.
