Elijah,

If this is a CIS-E car, as I think all 16v models are, I have one possible
thought.  I don't know if CIS-E does this, but with Digifant on my bus, the
idle switch will shut off the injectors above something like 2500rpm to save
fuel (like if you're coasting down a hill and using the engine to brake.)
If the idle switch is stuck on, it'll always think you're idling, and cut
off fuel at 2x00 rpm, turning Happy Fun Bus into Doesn't Go Anywhere Bus.

I know CIS-E can't shut off injectors, but maybe it can lean out the mixture
enough at the distributor to cause that problem?
