Okay, so as many know, I am now rolling in a 5.8L short block, with 5.4L heads, and a 3.6L KB in my 05 GT.
When I got the car back together last year after the last build it ran good. I tracked the car, sent data logs to John Lund for tuning. The car ran beast.
I have since added a pulley and that's all. The datalogs still looked good and no changes were made.
The car from the begining had a hard time starting when hot, but always started after a few cranks. (when cold it fires right up.)
Fast forward to about a year and 4000 miles later. The car is being a bitch, I am constantly getting random mis fire codes and when the car is hot it will not start at all. I have to let it sit for more then 30minutes before it will start again.
I haven't checked the injectors yet and honestly don't really know how or what to check and it was mentioned that I might be getting the gas tank to hot from the exhaust, since my muffler exits presently to the gas tank. However, it's been that way for a while without a problem.
So this problem just crepted up and started without anything really being changed...
I have changed the plugs, double checked the plugs gap, looked at the coil packs, did a complete smoke down leak test and there were no leaks.
I guess short of running the car hot and datalogging again I don't know what else to check or what else it could be. :/
Anyone have any ideas.
