Big problem Today I was driving on the freeway in my 1995 z28 when I lost power. First it shut off in traffic, then it just went limp and wouldn't rev above 3000 rpm and I had to floor it to get it to that and off the freeway. I pulled over put some more coolant in it since it sprayed all of it on the side and managed to limp it home. Anyone have any advice on what may have gone wrong here?

True limp mode is a PCM condition when the PCM loses most ALL of it's critical inputs. Very rarely does this happen. What most people consider "limp mode" is when one or two inputs are lost and the PCM defaults to a predetermined set of values (either by internal tables or making "educated guesses" from other sensors) for those inputs that are lost - it's basically just guessing. This is not "limp home mode", a term that is grossly overused and mostly misunderstood.

Thanks for clarifying too, I guess i was sorta right.
