Okay i just got my car back from the swap from hell.
Its going back monday beacsue its leaking coolant. whatever.
But this is the symptoms im dealing with.

Rough idle. sometimeswill die.
Kindof a bogg when crusing at a constant speed esp. at 55
Exhaust is thick and its not the weather to see your exhaust. Its white and smells normal
When you go through a pull and press in the clutch with no gas it will go all the way down to 200 rpm and bouce back to a regular idle 900-1100

Im thinking its a bad fuel ratio. I have no idea though. Can you throw me your opinions please.

Thanks

Cars stats for whoever does not know:
1996 Eclipse GS-T with 6-Bolt swap
4 Layer Head Gasket
Garrett T25 (better stock) Turbo
Nothing else done to it that would matter.

 

Serously any input

 

Do a boost leak check for the rough idling. I can't think of why your car would be smoking white and only smell like gas. Well, it could most likely be from the leaking head gasket.
