Ok so here's the specs:

88 CRX HF
Si Tranny
M/T
Si ECU


Car runs fine until about 15 miles, then it starts to surge, like fuel starvation or something. Turn it off, coast for a few seconds, car turns on and runs fine for another 15 miles or so.

Also, because of the Si tranny's different gearing (though I thought maybe the ECU change would fix it), even in 5th gear, the green shift light comes on at higher rpms...


Any clue?

Thanks.

 

Oh and it throws a VSS code. I'm going to change the VSS, but I'm not sure if the VSS would cause the surging.
