After advancin intake cam an then adjustin tensioner did the marks line up?
Is the guide for the cas on exhaust cam still there?
8 and 4 timing exactly the same. Got 8 port on sentra coupe and 4 port on sx. Have dne timing belts on both of them in the past.
Half moon for the CAS is there.
No more codes?
Have you done compression test?
New plugs?
Have you checked spark?
Have you double checked injector wiring and fpr connections?

Yes to all except compression test. Will do that tonight.
And clean your MAF, maybe a rat made a home there while the motor was out 😛
Also Cleaned and tried a spare.
Bro,that is one head scratcher! Just for interest sake,has the head been skeemed. If its skeemed to much it can also mess up getting the timing correct
Nope. I didn't remove the head and the car was running well for 4 years on this setup.
Got the same issue! I've just mounted h-dev stage 3 chip with whole setup. Has some problems with air leaks, needed new ECU etc and now Im in quite the same place.
When engine is warmed up Idle RPMs jumps betw 500-1200
Got problems with timing - once I've set it to 15deg and started the engine after some time all the marks were way off to the right - it look like I even cant get close to the first one from left.
I got inlet cam one tooth advanced - but guess this shouldnt couse the problems - afterall it isnt cam where CAS is.
Got the same error #34 (knock sensor - maybe I've damaged it when I was putting on intake manifold). Found some info that this can cause problems with timing.
cheers!
didnt draco have the same problems caused by a bad bearing in the cas? timing all over the place
when sensors give errors all at the same time, its something they have in common, ussually a bad earth.. so now that they are no longer giving errors does not neccesarily mean you dont still have a bad/high resistance earth..
might be worth a shot..
Actually Im pretty sure now it is because knock sensor, all symptoms match - jumping rpm's, too much fuel, problems with ignition timing and I got error 34 on ecu - knock sensor send signal to ECU which gives more fuel and retards timing for safety. The possibilities are:
1. broken knock sensor
2. problem with knock sensor circuit (maybe wire shield etc)
3. ecu
4. knocks in engine (but as I read - error 34 means problems with sensor or circuit not that there is a knocking - and I got problems on idle - there should'nt be any knocking on idle or if it is full throttle ride should damage engine right away).
The problem is knocking sensor is quite dificult to dismount - its under intake manifold. There is a way to trick the ECU - you need to connect ecu pin to the ground and get a 1M ohm resistor on that but if sensor is ok and the engine is knocking it can cause damage :/ Im not sure what to do. Im thinking about making a headphones connected to engine block and listen if there is knocking.
a little update - got off knocking sensor connector (it was real pain - couldnt get my hand on it) - it is tarnished as hell, maybe thats the reason (hope so). I'll clean it and do test ride.
nope still the same 🙁
