Hi all, Micra fans
I recently bought a 2000 Micra 1.3 with no maintenance history, unfortunately, and already changed and restored some stuff when time allows it.
To make a long story short, because of what I think was a misfire at low rpm when starting to move the car, I changed the spark plugs (really needed), then ignition wires but still there was that feeling so I turned to the distributor and found that it was leaking oil inside and couldn’t read some parameters to check it was fine. I decided to order a new one and while it didn’t arrived, I checked a lot of other components with a multimeter to see if their parameters match the Nissan service book / Autodata parameters.
There was some weird parameters that I may later describe but my main goal now is to install the new distributor and set the timing correctly.
I ordered a timing light also (asked for a digital one but the guy said it would not read well the Micra and the best would be a basic one, so I did).
Now, what I did:
Warmed up the engine
Stopped the engine
Hooked the timing light to cable 1 in the right direction
Disconnected the TPS
Started engine ( 2-3 min. later)
Blip the throttle 3x above 2500RPM
Let it idle (was at about 750rpm)
Checked the timing marks and it was far from 15 degrees, more like 30 BTDC
Turned the idle screw in the TB until having 600 RPM with the TPS disconnected
Checked timing again and its about the same. Turning the distributor make some change but never reach 15 degrees (maybe 20-25 degrees when retarded at maximum, can't remember exactly)
Now I’m a little lost and don’t know what should check next. Can it be a malfunctioning timing light, bad engine timing…? Have the disconnected TPS or the ICV some influence while setting the timing with the TPS disconnected?
Before checking the timing I took the ICV off to clean with carb cleaner and replace the oring. Does it need some kind of calibration to set the timing?
I also checked where the distributor rotor arm was pointing with the engine stopped but I’m a bit confused (or maybe not really want to believe there is a chain problem).
At TDC 0 (second mark from left) it is pointing cylinder 4
At TDC 15 (second mark from right) it is pointing cylinder 1.
My interpretation is: if it should be 15 degrees /600 rpm, it cant’ be 15 degrees/ 0 RPM.
What should I do next to get the correct timing?
Thanks in advance
