Crazy thing just happened, went to go start the car up and drive around trying to figure it out. As i was backing up into a parking space, i glanced at the AFR and it read 14.8. Put it in drive, same 14.8. Drove around the block, same 11.8 WOT 14.8 idle. Parked the car, went inside, came back out, started it again and there it was, LEAN AGAIN. BUT, i glanced at the coolant temp and it was reading 180 when it wasnt leaning out. Could the new radiator, which is a 1/4 inch thicker, in combination with my 180 tstat be keeping the engine from reaching proper operating temp? Would this lead to a lean condition? Im going to put this to the test tomorrow.
