OK....this is what happend....I was about to pull into my shop after a nice night and then the car starts to idle very ruff. I figured since I was driving slow down my street in a high gear MAYBE. Today i went out and it still does it. Clean the plugs check them for spark there ok. Changed the wires, there ok. What it does is skips at idle, skips the same as i rev it up but not pattern. But when i get high in the revs or the car starts to boost.. CRAZY SKIPPIGE, and under boost the car goes no where!! Checked all the coils for spark and they all spark...but the T2 coil if i unplug it there is not a huge difference in the skip. Im just wondering if anyone has had this problem or has any imput.

If you need more info about it PLEASE ask me.

check to see if your map sensor hose is off the sensor... near the master cylinder on the firewall.
do a compression check.

good luck,

Well last night i was up messing with it and I think maybe(HOPE) its the trailing 2 coil, because if I pull the plug wire the skip really doesnt change and when i pull any other the skip really gets back. I dont think its a blown motor, when i rev it up it skips like its a missfire. But I could be wrong. I have a buddy whos gonna let me try his coils, i am praying its gonna work!

I can get a video of what the car is doing if someone could help out?

Sounds like your leading coil is going south, the Cranes are known to do that to them. It is my understanding that the trailing really have little input except for emmisions, but i guess at idle they could be more important. Anyway, hope it's just a coil.
