I have this problem with my car where if i drive at a constant throttle amount (usually keeping the car at 0-1 psi) for about 5 seconds or more the car goes into some sort of limp mode. when it does this if i floor it it just breaks up like its pulling massive timing. but if i let off the gas and hit it again its fine. i have a 2005 evo GSR, i changed the plugs before realizing that it was only when i drove constant like that. i have a CEL but i though it was from my exhaust cuz i was getting those over and over. anyone know off hand?
