my 88 does it going into any gear but usually only once warmed up, drop it down into drive from a refire, dies, go up into reverse sometimes from drive, dies, go into reverse on a refire, dies.
I haven't figured it out yet. I have tried the relearn on mine, need to retry it, and I've changed the CTS, o2, removed the egr, and rebuilt the tb unit. my entire motor is new same with my distributor, my cap, rotor, coil everything.
The only things I have not yet changed is the TPS, IAC, knock sensor, MAP and the ESC module.
