civic VX d15z1 ignition timing

So i have been playing with my VX now for 2 years and cant seen to get the timing to act the same way as my novtec CRX.

With the mechanical timing believed to be correct and using a timing light, I can set my ignition timing pretty dead nuts on where it needs to be but the distributor is almost at its max advance. I mean only a hair away.

I just tried to advance the timing last night and I have the timing set at the advanced mark on the crank pulley but the distributor is completely maxed out at its travel.

Is this normal? I am following the timing procedure correctly and jumping the service connector while setting the timing. It just seems like I should have more adjustment than I actually do.

The car run fine and gets roughly high 40's and low 50's but has an occasional miss when hot at idle and in lean running at constant highway speeds.

I do not know the history of the motor whether anything has been machined. I did replace the timing belt and am fairly certain it is lined up perfect. I just want some input from other VX owners before I start tearing it back apart to check the mechanical timing for the third time.



Picture for interest

i think you're being OCD about the distributor position. if you have the ignition timing within spec, the objective has been met. whether the distributor is centered or not doesn't matter. and your mileage is good so that's a strong indicator that things are running relatively well.

the occasional miss at hot idle and lean running at hwy speeds could be a number of things other than ignition timing. for the hot idle issue, you can rule out the o2 sensor by simply unplugging it and driving like that for a while. if the miss at hot idle is gone, you've found the problem. if you replace the sensor and lean burn starts working properly, that's that.

also, when was the last time you replaced your cap, rotor, plugs, and wires?

The complete ignition system is brand new as process of elimination to solve the miss issue and it is still on going.

My O2 sensor was new 2 years ago but was not an OEM honda sensor. I will try unplugging it to see if it is the culprit

thanks for you help

Nice looking car. Great color. I have seen guys see similar problems when the timing belt has been installed incorrectly, IIRC. Check it?
