Engine idle problems and gear acceloration

[smd eclipse gst]

I have a 1995 eclipse gst with a lot of work done to the engine but the other day the thing started acting up.The first thing that happend was the rpms dropped while i was driving on the highway. I managed to get on a side road and the car completely died on its own when i pressed the clutch then it would start but die if i wasnt pressing the peddle. the rpms wouldnt go past 4500 and if i shifted into gear i would have to keep revving it up to keep it from dieing. I got it to a garage and changed the mass air flow sensor and the sensor that attatches to the cool air intake but its still doing the same thing and the computer isnt reading any problems. Does anyone have any ideas what might be wrong?

Check your intercooler piping, sounds like you were boosting and popped an intercooler pipe off.

Thanks i will have him look at that but is there any other possible solutions anyone can think of

Well all pipes are conected the fuel pressure is good and the spark plugs were changed same no changes any ideas?

Have you actually checked spark yet? Sounds like a bad coil pack and you're only running on 2 cylinders. Here's how you can test your coilpack.
