Limp mode - will happen (about four times now) after a short period of driving, and restarting the car will fix this and it doesn't re-occur during the drive afterwards. Also, nothing lights up and there's no warning. And, yes, I'm assuming it's 'limp mode' because the throttle is almost fully unresponsive and makes the car run like a mostly dead two-cycle Saab. I've done very little to the car mechanically after getting it, five months ago, except replace the air cleaners and the oil and rotated the tires, and had some front-end work to pass inspection here in MA. I've reset the throttle hoping this might work, but it didn't. I have very little info about the history of this car - a 2004 6-speed coupe with 75K - but all the service records I have access to have no indication of problems. Is it perhaps time for the (so common here) RCM replacement/upgrade? Any ideas from the enlightened group here? I have not as yet checked for codes, since nothing lit up on the dash.
