'88 2.1L Digifant
When I manually open the throttle QUICKLY to fully open while at the
engine compartment my van hesitates and doesn't react to the throttle.
Makes a pretty loud sucking sound from the throttle body.  It almost
acts like it's about to die when at full throttle and loudly "pops" or
backfires inside the throttle body  boot.  The boot and AFM actually
jump when it pops.

Throttle Position Switch has been checked with a voltmeter and "clicks"
Idle is great right now.  Within spec with no hunting.

Any thoughts?
I think this might be related to some of my recent cutouts with no luck
starting after it dies.  Got lucky one time after I pushed it to the
side of the road.  Started up after that but wasn't acting right.
Luckily I was 1 block from the house.

Thanks for your help
