Hia people

This is on KA-T with '95 KA24DE.
What could be causing timing to be 30 BTDC. I recently replaced turbo and IACV - have 22 HG of vacuum so I know it's not leaking, idle is bit high - about 1100. TPS is around 0.45v, MAFs works, car misfires.

If I rotate distributor to the left (front of the motor), it gives me 30 BTDC. If I rotate to the right - I get about 44 BTDC.

I've tried setting TDC over and over several times but same result.

Any help would be appreciated.

Thanks

Isn't the KA 20BTDC? Did it recently change? Was it right before?

make sure your tps is unplugged when you check the timing.

otherwise the ecu might have fed some advance in.
