So tonight when I was driving home from watching Total Recall (pretty good movie by the way) my car all of a sudden shut off. So I pulled off the main road and tried to start her up again. She refused to start and gave me the code 1256 (fuel injector 6) so I reset the computer by unplugging the battery and fired her up again. The RPM shot up to 4,500 and stayed there. So I put it in gear and inched forward and the rpm immediately dropped to normal. I creeped home and parked it. The idle rpm is now at 1,700. My question is, is this caused by the fuel injector just dumping fuel into the cylinder or some other fault with injector 6, or does this sound more like a vac leak? I did not find any vacuum leaks when I took the mani off to clean the ICV. Thanks for any help.
