Sounds like too me like it is a huge vacuum leak or electrical . Issues i have had with more or less the same:
Boost hose blown off IC pipe.
Map sensor disconnected
Injector connector has jumped off "well car was not running rich"
Faulty 3Bar FPR
Vacuum under the throttle body or the nipples on the intake were broken.
TPS
Poor idle due too ISV doing weird things.
Boost hose blown off IC pipe.
Map sensor disconnected
Injector connector has jumped off "well car was not running rich"
Faulty 3Bar FPR
Vacuum under the throttle body or the nipples on the intake were broken.
TPS
Poor idle due too ISV doing weird things.

It doesn't seem like a wiring issue to me, because i could drive it at low rpm upto 2psi of boost but it would be a huge struggle. and it would get worse the longer it runs and would get to the point it wont idle.
If you dont find the problem elsewhere:
I had a TPS fail in the full load position, so the DME ran the full load fuel maps. Killed the car, wouldnt restart due to too much fuel. Smoked black and could smell raw fuel in the exhaust.
Also recheck for vacuum leaks, holes in the backsides of the intake boots, etc. Have also had that keep a car from running.

maf connections are all good
and i have no idea how to check the ref sensors? explain how to please?
I want to try that, I've got a MSD one in the car now, but it's giving a pretty strong spark.

map sensor is connected properly been checked.
injector plugs where connected and all firing, it ran rich while(not before) this happened.
3bar FPR is new, and has 3bar fuel pressure and rises with boost.
i don't think the ISV has anything to do with the missfiring while driving and idling. that's more of a cold start thing.
Thanks for the list though.

Well I had a similar problem a week or two ago and posted about it. Large backfired and then no power. I checked the rotor the first time and it looked good no cracks. Then I checked it again a few days later and realized the small screw that holds it onto the engine was missing and I could freely twist the rotor back and forth and take it right off.... Not good. Lined up the hole and put a new screw in and it fired right up. It happened to someone else who posted on my thread as well....

yeah, I'm glad it's fixed. i ran it on idle simulated a few situations and found out it was the tps. when the tps was unplugged it was the same as how it ran.
Oh thanks! hahaha.
