Limp mode?

Last Friday I drove across town to pick up the wife and kids to head to the cottage. Car worked fine through 20 minutes of moderate traffic in 70F temps. I stopped and turned off the car for like 5 minutes to get them loaded, then started out again. I stalled the car backing out (way to go dad :banghead:), which is unusual, but I thought that it was just me. It starts right back up and I head out on the road. The car revs a little and then just bucks and jerks like it can't rev anymore than about 2000rpm. I can barely accelerate. I notice that when I push the clutch in and let it idle, the RPM's are around 1100 (not the normal 600-700 like when it is warm). There was no SES light at all. I drove for a couple of miles until I found a safe spot to turn off and stop. I noticed a very rich smell from the exhaust before I shut it down. I let it set a minute or two, and then restarted it. It has been fine ever since (about 300 miles so far). Does this sound like limp mode?

Anyone want to take a guess at a possible cause?

Hi, Nissan Largo going into intermittent limp mode (engine light flashes and power loss) sometimes on start up sometimes whilst driving ......not long after starting, best options please?
Yes I have aa 2005 nissan altima that is inimp mode right now it's very annoying I thought maybe it was a throttle sensor maybe. Anyway it won't go over 5 mph and I'm gonna try to reset it now. Let you know what happens in a few.
I changed the Max Air Flow sensor and didnt make any difference ....interestingly if I press down (pump) the accelerator pedal twice before starting it alleviates the problem...so maybe the throttle sensor?
