I would start with some basic diagnostics: Pull codes from the computer (see the stickies in the EEC-IV forum) and check the fuel pressure.

My '91 was doing the same. Codes showed a bad vacuum modulator valve. The leaky valve allows tranny fluid to get sucked up into the vacuum system where it ends up getting into the cylinders and burned. MrShorty is right, get the codes pulled and it will show up there if that is the problem. If so, don't ignore this problem too long cause the tranny fluid eats up the vacuum lines, then you get a cascade of problems.
