Car in question is an '89 turbo convertible, automatic, 94,000 miles.
When I first start the car, it starts right up but doesn't like to idle like it should. If I blip the throttle, it hesitates, catches and revs up, then stalls. It I hit the throttle harder, it really bogs down like it's ready to stall, then it catches and revs right up, then stalls again.
After the car is warmed up it still bogs down when I hit the throttle, but it does not stall. When I drive it however, many times it does stall when coming to a stop light.
It runs well at highway speed, although the turbo takes some time to hit the edge of red on the gauge.
I've installed new plugs, cap, and wires, cleaned the throttle and AIC, installed different NTC sensor, checked the TPS, and put in a known good AIC and AMM with no changes.
What am I missing?
