I Had the same problem with my 86, it would surge real bad especially when the AC was on. I replace the IAC and EGR and it helped a little. I then replaced the EGR vacum regulator solenoid, (thats what the haynes manual calls it, the dealer calls it some thing else) anyway it cured the surging problem. The dealer was the only one to have it. It's located on the side of the pax shock tower. It's not the side by side TAD/TAB solenoids.
