My 1998 cobra has pulled 3 codes, and 2 which have been fixed. The one that no one can help me with is code: P1516 - IMRC Inupt error (bank 1). If anyone can help me locate this problem, that would be awesome. My mods are: -K&N cone and cold air intake -62mm TB -Heads and Intake are ported and polished -Long tube headers -H Pipe w/ cat deletes -Flowmaster -4.10 gears -Superchips computer programmer. any help i could get would be awesome -Bruno-
