Do a ECU reset and see what errors show.

Did it not flash any codes up after the sequencing routine?

Anyhow, looks like it cleared - did it pulse the CEL on/off with evenly spaced flashes/voids, for the all clear?

nope plug the black leads together and count the flashes. 4 long 2short = error 42. 1 long 8short = error 18. ecu error codes can be found somewhere on here.

I think you may benefit more from finding the 'search' button.

Yep. There's a roadspeed sensor on the gearbox and if it gets no reading, then it tells the ECU to limit revs to around 4,500rpm.

As said, reconnect the speedo cable so the speedo works, and you should be good to go...
