I just got done replacing the ignition module 30 min ago start it up go to gas and it still hesitate gots me confusedTry gunning the gas from a dead stop if it shuts off it’s ignition module (sits on dizzy two screws)
It starts and runs fine just from time to time it will stall out ot hesitate when you accerlate fastI'd suggest a visit to the reference library on this site, pull up the 1987 emissions and drivability manual, find the chart for "cranks but doesn't start," and see what you figure out.
I've went thru almost every one besides the map even did every emissions hoseI had a similar a problem that turn into not even starting. The map sensor was bad. I would also check or replace other sensors in and around the TBI and engine, such as the TPS, Throttle Position Sensor. Maybe even the heat sensor in the block that fed the ECM.
