The transmission was completely rebuilt 23,000KM ago.
Actually, this morning i’ve dropped the car off to transmission specialist for its 20,000km interval service, he will also be checking it over for any issues and let me know.
I did advise him of an issue which has only occurred on a number of occasions, however only started happening after the sluggish/odd idle where when cruising between 60-75 and about to go up a hill, the transmission feels like its still in torque convertor lock and all power dies until it then drops down a gear to get the hill, whether this is sensor related or some other transmission issue i am not sure, but i gave this information to the transmission specialist to have a look for me.
I don’t know of any simplistic way of testing the timing, using OBD all i can see is timing advance degress, not sure how to actually check them.
I don’t have any chain rattles like others have (plenty on youtube).
Using your videos (i went through your troubleshooting) i checked vacuum using OBD and i cannot see any vacuum issues such as leaks or restricted exhaust.
I also did a heat check at both inlet and outlet of both CATS as per your videos.
When i replaced brake pads 2 weeks ago, there was no issues with the calipers, cleaned them and replaced the slider grease also.
If i put my AC on, the car idles a lot better and on occasion can run a tonne better also, if i suddenly turn the AC off after its been on, RPMs take a small dive and the car makes a stutter.
The power balance test didn’t give me any noticeable change in RPM when pulling each of them out, but i can see bank 2 fuel trims always sitting lean and the ECU compensate by using more fuel on that bank.
I might try swapping over the injectors from bank 2 to bank 1 and see if the fuel trim readings move with them, if it does that should be injectors if it, something else.
I’ll go back through and check these things again on the weekend along with checking all of the sensor readings again with my multimeter.

[quote=”barneyb” post=90033]I was thinking that the coolant temperature sensor could be giving some false indication to the fuel injection computer but the temps you report are normal.[/quote]
Yeah, any further things to try?
I know that the camshaft position sensor actuator solenoid is leaking, but i’m just going to get a new seal, pull it out, clean the oil out of the soleoind and put new seal in and see that goes.
Not sure if that would cause the issue though?
I get no CEL or engine lights so i’m not sure.

No i don’t hear any chain noise, i know the chain can become an issue, at this stage assuming mine is fine.
My car temps appear to be normal, however i don’t have a ‘standard’ temp range info to compare to.
Car typically sits between 90-105c when driving around.

[quote=”bustedbolts” post=89963]A faulty ignition module could cause those symptoms. I tend to think college man is on the rite track. I sounds like an electrical issue.[/quote]
I have swapped out each coil pack with another brand new coil pack to see if its made any difference at all, which was no. (1 at a time, not replaced them)
I also measured the resistance of each coil pack, which were all in spec.
Looking at my OBD data (excel sheet) i can see bank 2’s fuel trims are off, regardless of ignition, fuel trims should not be running lean.

[quote=”college man” post=89951]Try the power balance test. Also try cleaning you MAF/inlet air
temp sensor.[/quote]Did the power balance test alreay and cleaned MAF(IAT contained) also.

[quote=”college man” post=89946]Try spraying the ignition wires with water to see if the engine
starts running rough. If you can turn the lights out and look for
arcing.[/quote]Car is coil pack on spark so no ignition leads.

[quote=”college man” post=89835]here is a link for performance issues. what year is the car?

I’ve gone through most of that troubleshooting and cannot find anything, except for the cam position sensor actuator solenoid (as its listed in the workshop manual)
Its a 2004 model.
