code 11 is when your ecu gets it power cut. Make sure it has power, and keep putting in/taking out the jumper and turning the key on. Itll eventually get rid of the code 11 and give you some real ones. I think the car might have to run first tho. So start it up. It does sound like either a boost/vaccum leak, Bad maf, or bad injectors thou. The other fuel injection sensors cant really affect it that much except for the maf, cam position sensor, or throttle position sensor. Itll even run with most of them unplugged. Goto the tsrm and look for trouble shooting with a volt meter and test all of them by measuring their resistance. Volt meters can be extremely usefull for FI vehicles.
