TB is clean.
MAF seems to read correctly according to the Torque app, but, hasn't been cleaned.
I'll do that tonight.
Upstream was replaced a year ago, and has always shown a weird trace, rather than a smooth sine wave. It has always looked weird on a graph in real time (I'll post pics).
Downstream is original and has been dead for 12 years with no real issue.
TPS reports responsively on the app.
Fuel pressure stays perfect.
