Yea i threw a MIL too but it was p0161 o2 sensor heater circuit malfunction bnk 2 sensor 2 basically my o2 needs replacing. I believe your cats are out a good test is to get under there and hit it with a rubber mallet and listen to any rattling which there isnt supposed to be.

yea i replaced that gasket but im still leaking and to find out the coolant filler has a crack in it but has been "repaired" with sealant or gasket maker

hey guys just wanted to add something i have a ls400 same problem i found out that there was coolant in between the v8 by the starter and it was leaking down through the tranny to the inspection plate and i have no heat also. and the coolant filler was leaking does any one know how to remove it i cant get it to budge off the front bypass HELP!!!
