This thread got me curious, so when I was out for a quick buzz into town on some errands, I did snap to WOT a few times, and did not detect any stumble. RPM was just off idle when I went WOT several times, but no stumble.

The car was fully warmed up, and it had done a couple 7k run-ups prior to the off idle WOT "test", for what it's worth.

I had some stumbling problems when I got the car, and I ran down a few air (vacuum) leaks, re-torqued the intake plenum, etc, and later found a vacuum hose disconnected under the chin of the TB (90 ZR-1). The injectors are new, according to the guy I bought it from, but chewed plug wires (mice) was the final "fix".

If ya want, I'll take my scanner along next time and do some more WOT and print out the results; TPS, etc. and see how it compares to yours or some others, perhaps.
