I forgot to mention, if you are having an ignition switch problem(which is quite common) the tac module is fed from ign 1 power which feeds through the ign switch. Never seen an ign switch failure cause A reduced engine power problem but anything is possible. Also check that the throttle blade moves freely, remove the air intake hose and check by hand, may just need to be cleaned. If it binds at all it will set that code. Have your trusted mech also check pin grips and wiring to the tac module(remove any tape from harness and inspect harness) Any other questions feel free to ask. Hope it all works out for ya.
