I had the same problem with my 93. What happened was that there was carbon in the EGR valve that needed to be taken out and I had the EGR valve replaced aswell.

Also do you usually have tons of smoke from the exhaust at start up? That's another thing that happened.

Check your distributor cap as well. It may have a crack in it. I had that happen with my old Volvo and after I replaced the cap, it started up no problem.

Just an idea...
