If my memory serves me right, I had a turbo timer short out under the console and caused this before on my car. Look there also. check nipple connections on back underside of Intake by the firewall. Most common hose that came off on me was front right on intercooler. Keep us posted.

 

If coil goes out, sounds like a motorboat at idle.

 

also when i come to a light and sit at idle, it will idle so low it dies, especially after getting on it

 

do you have all these mods and a stock exhaust???
that could be a problem....when i bought my car it was modded and the guys before me obviously sold his exhaust and put the stock one back on with out retuning or anything and when i went to dyno it it was running wayyyyy lean then i put a 3" cat-back on it and tadaaaaaa the car was runnin perfect

 

so jst got home from the shop, I took off the intake and the turbo is going out, I can move the shaft side to side and actually touch the fins to the walls, I know that is only catching and stuttering under heavy boost, but how would that cause lean and misfire.
I can get it rebuilt local for 350 or get a rebuilt on for 350 so a new turbo it is.
