Here is the story
TPS sensor totally out of specs measurament and distributor a little turn conterclock wise to compasate cool start problem. . the car work but lack of power, no good throttle response,
here what I did to try to correct this problem. but the car get worst
Here what i did.
set TPS to spec volts. 0.54 at idle 4.5 at WOT.
new IAC valve
the car have cool start problem. bad idle when cool engine.
once the engine get hot idle get better in Parking position.
move the gear to drive. the car stal to the point of engine stop
same goes for revers gear. imposible to drive the car because the engine stop.
only get good idle when engine hot and parking gear.
fuel preasure ok all the time.
check for vacuum no leak found.

My advice is to set the distributor back to stock setting and not try to "fix" it by tweaking this, that or the other. Depending on what mods you have, getting a real tuned chip will serve you better. At which point, your idle issue might go away or be easily adjusted. We can't adjust the idle properly with the distributor being out of spec since that also affects idle.
