Message	However if the ECU is not happy with the O2 Signals, it might not settle into Idle Mode.. I've also had that happen.. My '95 NA with JWT 16 Bit ECU would lope at hot idle. Changed to ECU to an 8 bit NA Stock ECU and it quit the 'Stumble/Lope'.. bit the performance was lacking.. so the JWT went back in.. Fast Foreward 3 years.. the NA has had a complete re-haul of the Engine ( 200K blown head gasket ) Bored/pistons.. all the IAC type stuff has been cleaned and new PCV valves.. SAME O2's and JWT 16 bit ECU back in.. NO LOPE.. Go Figure.. Cj
