Off to the mechanic for new tyres so will see if I can get the tps readings. Also found an electronics guru in town so might see if I can get him to look at the black boxes on the throttle bodies.

I actually watched it at a stop light, start at idle, around 1450, and move to around 3800 RPM.
TPS, at rest is .64V, but I don't know what it is at WOT. I'll take a look at the stepper arms but is there anything else I should check? All plugs just got a healthy dose of dielectric grease (thank you amazon).
