Basically as the title states, I am running rich at idle according to the AEM Wideband (13.2 - 14.2), and the knock gauge (old boost gauge on dash) is maxing out under 1 to 3 psi boost. If I am driving at a steady speed say 55 mph and accelerate just enough to get 1 to 3 psi, the engine completely changes tone like it is bogging down, and my knock gauge maxes out. If I left of the gas quickly and get back into within 1 to 2 seconds, the knock usually goes away. I have checked for boost leaks and located 2 which have been fixed around 1k miles ago. No more exist now. The knock sensor is about 1 year old from Autozone.
Also to add to the problems.... my engine is constantly running hot when the temp outside is above 60 degrees. I have to turn my heater on to cool it down which sucks! The radiator, hoses, radiator cap, water pump, and thermostat are all brand new. I got the water pump from Orielly. After a 30 minute drive or more without getting into boost, I can pop the hood and the manifold right where it goes into the turbo will be glowing red hot. I have had this problem since I put the turbo on which was a brand new Evo 16G from STM which was maybe over a year ago. I am running a 2g manifold if that helps any. Under acceleration above 5psi boost, I smell antifreeze within a few seconds. No leaks have been found yet. Brand new headgasket and ARP head studs torqued at 90ft lbs using the correct lubrication. They have been re-torqued as well.
Last but not least, my AEM wideband O2 is going crazy!!! Sitting at idle, it bounces between 13.2 to 14.2. When driving down the road at 55 under normal acceleration, it bounces between 13.8 to -.-- over and over every second. Under boost, it reads 10.8 to 11.1.
Any feedback on any of the above problems is appreciated! My first thoughts is the turbo has gone bad already which is causing all these problems or my 560cc injectors are not flowing correctly.
