Hmm, my compression numbers are higher than spec at 200-210 across all 6. Ive been tracking a rough idle, and using conzult dialing the idle RPM to 900 the ecu sets ignition timing at 0 deg BTDC and that's the only way to have a reasonably smooth idle.
But with the TPS unplugged the idle is smooth in any range of idle RPM and the ECU locks the ignition timing at 10 deg BTDC as it should with a 96.
