Idles, but dies giving throttle

[mtwebs]

Just scored my first Sidekick!

1993, 4 door LX 16V. Pretty good shape, except no spark when I bought it ($400USD).
New igniter, replaced all underdash fuses, checked dist cap, rotor, connections, etc. Got it to run when trying rotor in all 3 positions.

It idled at around 3,000 rpm, and would immediately die with throttle opened. Literally could push throttle to floor and hold it, no RPM increase, just died like ignition turned off.

Checked throttle body (clean, no damage), installed TPS from a known running vehicle, set .026 gap at screw with DMM, reinstalled - no change.

Pinched IAC hose tight, it idled down,(YAY!) and got to around 1,000 RPM or below via bleed screw.

Checked hoses, tried propane torch (not lit!) everywhere reachable on intake side, no changes in idle.

Starts easy enough and idles with IAC pinched.

Still dies when opening throttle, though.

I just pulled the IAC to inspect and clean.

Am I on the right path? Pointers?

Thanks so much. Really appreciate fixkick.com and this forum. Wealth of information!
