I took the wagon for a run down old pac yesterday.
It is low on power compared to other NA B230s I've driven, but it does drive fine at higher RPM. At low RPM/idle/feathered throttle, it runs poorly. I'm now getting a 2-1-4 code on the EZK diagnostic port, which means "RPM sensor signal absent intermittently".
Given all the
work I had to do to make the RPM sensor align with the drilled flywheel (it was drilled incorrectly), I'm just going to start there and put an OE LH-2.4 flywheel in, which
@Philia_Bear has lent me.
