Long story short i returned a cracked header for warrenty. The guy i talked to said that it looked like (judging by the metal discoloration) the cause of the crack was my jeep running lean, causing hotter than normal combustion temperatures. This sortof makes cents to me because i have heard that jeeps with intake and exhaust work done to them sometimes run lean. My question is: To my knowledge my jeep has never had the addaptive memmory reset by the previous owner (installed the CAI), and i know that i didnt reset it when i installed my bigger (what ever factory TB is when bored out) throttle body (out of fear of mpg decreasing). Do you think reseting (flashing) the addaptive memmory would fix my problem, or @ least b worth my time?
