First nice weekend of the year, I went to start my 2000 Boxster w/ only 20K miles on it. Battery was completely dead so I put a jump on it. It took several tries but it eventually started. Ran rough but as expected because several attempts of starting loaded it with fuel. I went to back out of garage and the vehicle stumbled. I went to take a nice easy drive around to clean out the excess fuel and I couldn't go past 11mph. Not in first gear or in second gear. Engine runs smoothly, no misfire, no CEL, but it's just limited like the engine controls is in some protection/valet mode. I figured 11mph is 20kph so it is controlling to that speed. Like I said, no check engine light and the vehicle runs relatively smoothly, to 11 mph. At idle, it will run smoothly at 1000rpm then dip below and run rough and keeps cycling that way. Anyone seen an issue like this? Thanks for your help.
